When it comes to size, the KitchenAid K150 is surprisingly compact compared to other full-size blenders on the market. It stands at just 14.8 inches (37.6 cm) tall, making it a breeze to fit on your countertop without taking up too much vertical space. The width is also impressively narrow, measuring in at 7.2 inches (18.2 cm), and the depth is a reasonable 9.1 inches (23.1 cm), allowing you to tuck it away in a corner or against a wall without hogging too much real estate.

And the best part? It's incredibly light, weighing in at a mere 8.4 pounds (3.8 kg), making it easy to lift and move around, even if you're not exactly a weightlifter.

One of the major benefits of the KitchenAid K150 is its storage-friendly design. You can leave it proudly on your counter, ready to whip up a smoothie or puree at a moment's notice, or stash it away in a cupboard when you're not using it. In fact, it's remarkably similar in size to the Oster Pro 1200, another popular blender on the market.

Speaking of the Oster Pro blender, it's also on the smaller side for a full-size blender. It measures in at 14.4 inches (36.5 cm) tall, 7.0 inches (17.9 cm) wide, and 7.5 inches (19.0 cm) deep, making it another great option for those with limited kitchen space. And at 7.9 pounds (3.6 kg), it's even lighter than the KitchenAid K150!

Ultimately, both blenders are designed with convenience and storage in mind. They're perfect for those who want a powerful blender that won't take over their kitchen, and can easily be tucked away when not in use.

When it comes to jar capacity, the KitchenAid K150's 48.0 oz (1,420 ml) container is definitely on the smaller side for a full-size blender. In fact, it's smaller than many of its full-size blender cousins, like the KitchenAid K400. This means you'll need to blend in batches if you're making large quantities of your favorite smoothie or puree. However, the smaller size does make it easier to store and maneuver, especially if you have limited kitchen counter space.

But what about the jar itself? Its jar is made of plastic, which is a bit of a mixed bag. On the one hand, plastic is lightweight and easy to handle. On the other hand, it can be prone to scratches and discoloration over time. The good news is that the jar and non-removable blades are safe to wash on the bottom rack of your dishwasher, making cleaning a breeze. The lid and center cap, however, are only top-rack dishwasher-safe, so be sure to separate them when washing.

Now, let's talk about the Oster Pro 1200. Its main jar has a 48-ounce capacity, which is similarly on the smaller side for a full-size blender. But here's the cool thing: it also comes with a 24-ounce personal jar, which is perfect for making individual servings or blending small batches. And when it comes to the jar material, the Oster 1200 blender takes a different approach. The main jar is made of glass, which is a great choice because it's less prone to scratches and discoloration than plastic. Plus, it's just a more premium feel, you know?

The smaller personal jar, on the other hand, is made of plastic. But don't worry, both jars, the blades, and the lids are fully dishwasher-safe, making cleaning a snap. You can just toss everything in the dishwasher and let it do the work for you.

So, when it comes to jar capacity, material, and cleaning, both blenders have their pros and cons. The K150 has a smaller plastic jar that's easy to handle, but may not be as durable as glass. The Oster has a glass main jar that's premium and durable, but also comes with a smaller plastic personal jar. And while both blenders are relatively easy to clean, the Oster Pro 1200's fully dishwasher-safe design makes it a bit more convenient. Ultimately, it's up to you to decide what matters most in a blender!

When it comes to the jar's lid, both the KitchenAid K150 and the Oster Pro 1200 have some cool features that make blending and cleaning a breeze. Let's start with the KitchenAid blender. The lid is made of plastic, which is lightweight and easy to handle. But what's really clever is the rubber-like grooves on the bottom of the lid's lip. These grooves create a friction seal that helps keep the lid securely in place while you're blending, which is super important when you're dealing with hot or thick mixtures.

One of the most convenient features of the K150's lid is the removable center cap. You can take it out to add food or ingredients mid-blend, which is a total game-changer. Plus, the center cap doubles as a measuring cup for up to 45ml or 1.5 ounces, which is super handy when you're trying to get precise measurements. And when it's time to clean up, you can just pop the lid and center cap into your dishwasher's top rack for an easy clean.

Now, let's talk about the Oster Pro 1200's lid design. The main jar has a two-part lid with a clear centerpiece that you can remove to add ingredients mid-blend, which is similar to the K150 blender's design. But what's really cool is that the Oster Pro blender 1200 also comes with a resealable to-go lid for the personal jar. This lid screws onto the jar, making it perfect for taking your smoothie or protein shake on the go. However, the cover for the spout feels a bit flimsy, which is a bit of a bummer.

Overall, both blenders have some great lid design features that make blending and cleaning easier. The KitchenAid K150's lid is super secure and easy to clean, while the Oster Pro 1200's lid has some convenient features like the removable centerpiece and resealable to-go lid. However, Its lid could be improved with a more sturdy spout cover.

When it comes to build quality, the KitchenAid K150 blender is a clear winner. While it's true that most of the blender is made from plastic, including the motor base and transmission, it still feels incredibly solid and well-built. In fact, it's even better built than the KitchenAid Diamond, which is a more premium model. 

The jar's transmission gears are made of sturdy steel, and the control dial is made of metal, giving it a premium feel. When you're blending, the jar feels rock-solid and stable, which is exactly what you want from a blender.

The only downside is the handle, which doesn't feel particularly comfortable to hold. But overall, the KitchenAid K150 exudes a sense of quality and durability that's hard to ignore.

On the other hand, the Oster Pro 1200 blender has a more mediocre build quality. The buttons on the front of the motor base are clicky and easy to use, and the motor base has vents to allow heat to escape, which is a nice touch. The main jar is made of thick, sturdy glass, and the handle feels solid and comfortable to hold. The plastic personal jar also feels decently well-built, and the resealable lid is a nice feature.

However, things start to fall apart when you look at the gears and blade assembly. The design just doesn't feel very durable or well-thought-out. The gear on the motor base is square-shaped, but it fits into a star-shaped gear on the jar, which means they don't fit together perfectly. This can cause more friction and wear on the gears over time, which is a major concern. Plus, the blade assembly feels loose and poorly made, with a plastic tab that feels like it might break if you put too much pressure on it.

The blades are only held in place by a rubber gasket that has a loose fit, which can lead to ingredients getting trapped and making cleanup a real pain. And to make matters worse, there's a small gap between the gasket and the metal plate of the blade assembly, which can trap even more ingredients. On the plus side, the blade assembly is easy to remove and clean, but it's not very reassuring to know that you can't use the blender safely if you lose or damage the gasket.

Overall, if build quality is a top priority for you, the KitchenAid K150 is the clear winner. It's a blender that's built to last, with a solid construction and premium materials. The Oster Pro 1200, on the other hand, feels more like a budget-friendly option that's trying to cut corners to save on cost.

When evaluating the blade assembly and speed of the KitchenAid K150 and Oster Pro 1200, several key differences emerge. This small blender's blade assembly features four sharp blades designed to effectively process ingredients. While the blades cannot be removed from the jar for cleaning, they are dishwasher safe when placed on the bottom rack. This design choice simplifies cleaning, but may not provide the same level of thoroughness as a removable blade assembly.

In terms of speed, the KitchenAid small blender boasts a minimum speed of 4000 RPM and a maximum speed of 11,700 RPM, powered by a 650 W motor. The blender's speed adjustment is limited to three preset options, with no increments between the speed markings. This design may not provide the same level of precision as a blender with more nuanced speed control.

The Oster Pro 1200, on the other hand, features a removable blade assembly that is compatible with both included jars. The assembly is held in place by a rubber gasket, making it easy to disassemble the blender for cleaning. The manufacturer claims that the blender features "dual-direction technology" that allows it to reverse its blending direction to clear jams. However, this feature was not noticeable during testing, and it is unclear how it benefits the user.

In terms of speed, the Oster blender has a minimum speed of 4,500 RPM and a maximum speed of 18,000 RPM, powered by a 1,200 W motor. The blender's speed adjustment is limited to three preset options, plus pulse mode. The blending speed is actually the fastest when using pulse mode, which may not be ideal for all users.

Making Soups

Oster Pro 1200's Overall Scored in this feature100%

The KitchenAid K150 is a soup-making machine. You can hot blend with this blender, which is perfect for creating a smooth, creamy soup. It can handle even the toughest ingredients, like kale and broccoli, with ease. The blender's powerful motor and sharp blades make quick work of fibrous ingredients, leaving you with a silky, grain-free blend. The only downside is that the 48-ounce jar is on the small side for a full-size blender, which can make it a bit tricky to clean by hand. But don't worry, the jar and lid are both dishwasher-safe, making cleanup a breeze.

On the other hand, the Oster Pro 1200 is also a great choice for soup lovers. You can use the 48-ounce main jar to process hot ingredients directly from the pot or pan, which is super convenient. And like the KitchenAid K150, it's great at blending fibrous ingredients like kale and broccoli into a smooth, pureed soup. Plus, the Oster Pro 1200 is a cinch to clean, which is a major bonus. However, the blender's construction is a bit of a letdown. It's not as sturdy as the KitchenAid K150, which might be a concern for some users.

If you're looking for a sturdy, high-quality blender that can handle hot blending with ease, the KitchenAid K150 might be the way to go. But if you're looking for a more affordable option that's still great at making soups, the Oster Pro 1200 is a great choice.

Nut Butter

Preparation is a crucial part of making nut butter, and both blenders require some effort in this regard. The KitchenAid K150 scores a 6.5 out of 10 in terms of preparation ease, while the Oster 1200 Pro also scores a 6.5. This is because both blenders need to be stopped frequently to scrape down the sides of the jar and ensure everything gets mixed properly. However, the Oster 1200 Pro requires you to remove the lid and stir the ingredients a few times, which can be a bit more tedious.

When it comes to the final product, both blenders deliver smooth and spreadable nut butter. The KitchenAid K150 takes the lead with a score of 9.5 out of 10 for nut butter texture, while the Oster 1200 Pro scores a close 9.0. The blender K150 produces a remarkably smooth consistency, making it perfect for spreading on toast or using in recipes. The Oster 1200 Pro also produces a smooth nut butter, but you might find a few tiny pieces of unprocessed nuts trapped under the blades.

One key difference between the two blenders is their speed settings. The KitchenAid K150 has slower speed presets that are ideal for making nut butter, as they prevent the ingredients from flying to the sides of the jar. The Oster 1200 Pro, on the other hand, has a more powerful motor that can blend ingredients quickly, but may require more frequent stopping and stirring to get the desired consistency.

In the end, both blenders can make delicious nut butter, but the KitchenAid K150 has a slight edge when it comes to texture and ease of preparation. If you're willing to put in a bit more effort and don't mind stopping the blender frequently, the Oster 1200 Pro can still produce great results. 

Crushing Ice

The KitchenAid K150 is a beast when it comes to crushing ice. This blender is built to last, and it shows in its ability to make bar-quality ice quickly and easily. Whether you're making a frozen margarita or a slushy smoothie, the KitchenAid K150 has got you covered. 

However, it's worth noting that the manufacturer recommends not adding more than half an ice cube tray's worth of ice cubes at once. This means that the blender's ice-crushing capacity is a bit smaller compared to some other full-size blenders on the market, like the Ninja TB201 and Ninja BN701 Professional Plus Blender. Still, it's a great option if you're looking for a reliable blender that can handle ice with ease.

On the other hand, the Oster Pro 1200 is also very good at crushing ice. Despite its lack of sturdiness and durability, it's able to make excellent crushed ice - as long as you follow the manufacturer's guidelines. 

And speaking of guidelines, the manufacturer recommends only adding up to six ice cubes to the jar at once. This is a pretty significant limitation, especially if you're used to making large batches of frozen drinks. However, if you're willing to work within these constraints, the Oster Pro 1200 can deliver some amazing results. In terms of ice-crushing ability, it's on par with blenders like the Vitamix A3500 and Ninja TB301 - which is no small feat!

If you're looking for a sturdy, reliable blender that can handle ice with ease, the KitchenAid K150 might be the way to go. But if you're willing to work with a blender that's a bit more finicky, the Oster Pro 1200 can still deliver some amazing results.

After checking both powerful blenders’ control interfaces, I found some similarities and some key differences. 

The KitchenAid K150 has a pretty simple control panel, with a speed dial that lets you choose from three different speed presets. There's also a pulse/turbo mode button, which gives you an extra burst of power when you need it. One thing to note is that there's no on/off switch, which might be a bit unusual for some users. However, the blender does have a hot blending feature, which is great for making soups and other hot liquids.

One of the downsides of the KitchenAid K150 is that it only has a single "crushed ice" setting, which might not be enough for users who want more control over their blending. Additionally, the third speed setting can be used as a cleaning cycle, but it's not a dedicated self-cleaning program. If you're looking for a blender with more preset programs, you might want to check out the Calphalon ActiveSense.

On the other hand, the Oster Pro 1200 has a more comprehensive control panel. The motor base features controls for three speed settings: 'Low,' 'Medium,' and 'High,' along with a separate button for the pulse mode. You can also choose from three blending programs: "Green/Frozen Smoothies", "Food Chop/Salsa", and "Milkshakes". This gives you a bit more flexibility and control over your blending, which is great for users who want to make a variety of different recipes.

One of the nice safety features of the Oster Pro 1200 is that you need to press the on/off button to turn it on before it will run. There's also a light that flashes when the blender is "on", which is a nice touch. The manufacturer advertises the blender as having seven speed settings, which seems to count the blending programs, pulse mode, and speed presets separately. Overall, the Oster Pro 1200 has a bit more to offer in terms of features and controls, but both blenders have their strengths and weaknesses.

The K150 blender is generally easy to clean, especially when it comes to non-sticky foods like smoothie residue. A quick rinse is usually all it takes to get rid of any leftover bits. If you need to do a deeper clean, a 60-second blend of hot water and soap can work wonders. However, things get a bit trickier when dealing with sticky foods like almond butter. In this case, you'll need a soft dish sponge to get into the nooks and crannies of the lid and jar walls. And speaking of the jar, it can be a bit of a challenge to clean due to its non-removable upward-pointed blades.

On the other hand, the Oster 1200 Pro blender is a breeze to clean. To get started, simply add some warm water and soap to the jar and run the blender on high. This will help loosen up any stuck-on food particles. Then, use a sponge to wipe down the jar and blades. The best part? The blade assembly is removable, making it easy to clean and maintain. This is a major advantage over the KitchenAid K150, which has fixed blades that can be a pain to clean.

That being said, some people may not love the idea of taking apart their blender to clean it. If you're one of those people, you might prefer a blender like the Blendtec Designer 725, which is designed for easy cleaning without disassembly.

In the end, both blenders have their own unique cleaning quirks. But if you're looking for a blender that's easy to clean and maintain, the Oster 1200 Pro might be the better choice. Its removable blade assembly and easy cleaning process make it a winner in this department.

The K150 small blender is a pleasant surprise when it comes to noise level. In fact, it's quieter than many full-size blenders we've tested, including the Vitamix 5200 and Vitamix 5300. When we put it to the test, it registered a respectable 88.8 decibels (dba) on our noise meter. To put that in perspective, a normal conversation between two people is around 60 dba, while a vacuum cleaner can reach levels of up to 90 dba. So, the KitchenAid K150 is relatively quiet, making it a great choice for early morning or late-night blending sessions.

On the other hand, the Oster 1200 Pro blender is a different story altogether. This blender is loud, registering a whopping 97.3 dba on our noise meter. That's significantly louder than the KitchenAid K150, and even louder than many full-size blenders we've tested. In fact, blenders like the Ninja Professional Blender 1000 and the Ninja Detect Power Blender Pro are actually quieter than the Oster 1200 Pro, even at their maximum speed.

So, why is the Oster 1200 Pro so loud? One reason may be its powerful motor, which is designed to handle tough blending tasks with ease. While this motor is great for getting the job done, it comes at the cost of increased noise level. If you're planning to use your blender during quiet hours, you may want to consider the KitchenAid K150 instead.

In the end, noise level is just one factor to consider when choosing a blender. But if you're looking for a quiet and unobtrusive blender, the KitchenAid K150 is the clear winner. Its relatively low noise level makes it a great choice for blending at any time of day.


The KitchenAid K150 and Oster Pro 1200 are both high-quality blenders that can help you achieve your blending goals. While they have a few things in common, they also have some important differences. The KitchenAid K150 is a great choice for those who want a powerful and durable blender with a sleek design. On the other hand, the Oster Pro 1200 is a great option for those who want a blender with advanced features like dual-direction technology and a wide range of speed settings. Also, it’s easy to clean than K150. 

Ultimately, the choice between the two blenders will depend on your specific needs and preferences. We hope that this comparison has provided you with a clear understanding of the features and benefits of each blender, and has helped you make an informed decision. Whether you choose the KitchenAid or the Oster, you can't go wrong with either of these top-notch blenders.

We recommend buying Kitchenaid k150 blender since it’s perfect for multiple purposes like cruising ice, hot blending, and the most important part is its sturdiness.
