The KOIOS 4-in-1 is easily distinguishable from the All-Clad and the difference between them comes from the overall design. While the KOIOS 4-in-1 is mostly made of plastic which isn't the sleekest, the All-Clad will impress you with its rock-solid construction that you won't find anywhere else.

As good as its built quality is, the All-Clad doesn’t really have much to match the competition in terms of versatility. Meanwhile, the KOIOS 4-in-1 comes with several extra niceties like the whisk attachment, which did allow it to gain an advantage in the tests of making mayonnaise and beating egg whites. In the other tests, neither of them produced top-quality outcomes, but for the most part, they were above average.

  • Result: Slightly Chunky
  • Suction: No

None of the low-range blenders we tested could yield the silkiest puree in 30 seconds, but we think the KOIOS’ results will still be acceptable to most home cooks.  In particular, the soup looked silky but when we ran it through a strainer, too many tiny bits were left behind. Nevertheless, we were still satisfied with this blender, given its consistency and smooth operation. Just in case you’re expecting for silky, restaurant-quality pureés, we recommend the Vitamix 5-speed.

  • Result: Slightly Chunky
  • Suction: Slight

The All-Clad’s strong motor pulverized carrots and pumpkins easily, but it fell short in handling leafy veggies. After 30 seconds of blending time, several chunks of celery remained quite intact because they got lodged in the blade guard’s holes. The blender somehow couldn't draw them toward the blades. Ultimately, the soup failed to reach the perfect texture. At this price point, we expected a restaurant-quality soup rather than this grainy one.

The manufacturer recommends this blender not be used to process frozen fruits. That fact made us skeptical about its overall capability. After much deliberation, we decided to stick to the initial plan, putting it through our frozen smoothie test anyway. To our surprise, its result was nearly the same as that produced by the Vitamix 5-speed immersion blender. 

In less than a minute and a half, it churned out a frozen smoothie that was flavorful enough to entice our taste buds. The drink didn’t have a velvety smoothness; it was a bit grainy since the kale wasn’t entirely liquified. Despite that, it was still a sweet, creamy combination that we loved to sip on.

In this test, the All-Clad 10942212300 blended the thick mixture without struggle. It completed its task in about one minute, which was much faster than average. All the frozen fruits were broken down into the finest of bits. There were a smattering of kale flakes in the final smoothie, but that didn’t affect our taste buds.

The KOIOS made short work of incorporating egg yolks and canola oil, churning out a harmonious texture in just over one minute. Apart from being one of the fastest, it was also among the few blenders in our test that produced exceptionally smooth emulsification. Our mayonnaise came out thick, creamy, and spreadable. For such a low-priced hand blender, this performance could hardly have been better.

  • Result: N/A
  • Suction: N/A

For this test, we tried to whisk together three egg yolks and 240ml oil using the blending wand. To avoid broken mayonnaise, we ran mostly at medium speeds and only sped up once the oil started emulsifying. Each blender is put through the same testing procedure. However, this was the only hand blender that couldn’t reach the emulsion stage. After about 2 minutes of operating, all we got was a jumbled mixture that looked more like broken eggs than an emulsion.

Technically, it’s hard to conclude whether or not the All-Clad can make mayonnaise in the real kitchen since there are many external factors that prevent the emulsion from forming. This also means that the emulsifying capability of this blender is still an open question.

It was simple and easy to put together all the ingredients for a preservative-free milk using the KOIOS. Since this blender ground the nuts pretty evenly, our drink came out silky and creamy. That said, blending didn’t run smoothly; the blending beaker was too small, causing the liquid to overflow every time we moved the blender around.

If you intend to buy the KOIOS for drink preparation, don’t use the beaker that is included in its set.

  • Grinding Time: 1 min
  • Result: Fine
  • Suction: Tight

Considering how evenly and easily it blended frozen fruits, we weren’t surprised that the All-Clad had no trouble pulverizing raw nuts. After the mixture reached our preferred consistency, we extracted the liquid using a nut milk bag. The pulp was finely ground, so the final drink looked creamy and very milk-like. It tasted rich and almondy, exactly as it should. The whole procedure lasted one minute, which was 50 seconds faster than the worst one, the Chefman 6-in-1.

  • Suction: No

The KOIOS’s whisk attachment worked well — we got the perfect meringue out of the egg whites we beat with the whisk attachment. Its metal wires are bouncy and agile, so they’re flexible enough for whipping and fluffing. However, we can’t say for sure whether those wires will hold up to thick batters for bread doughs or baked cakes. 

On a pragmatic note, the whole beating process lasted nearly 3 minutes, but it didn’t cause hand fatigue like some models, namely the Mueller Ultra-Stick or the BELLA 10-speed. We felt entirely comfortable in that prolonged operation, from start to finish. Indeed, using this blender for preparing airy, creamy desserts will help you stay creative without springing for an expensive specialty device.

Any whipping task will likely exceed your All-Clad’s capability, but that’s mainly because it doesn't include a whisk attachment. We haven’t tried a single hand blender that could whip egg whites using just the blending wand. More often than not, the whites never even reach the soft-peak stage. In the end, we were left with a cloudy liquid composed of two separate layers of bubble film and eggy water.

With dimensions of 17.5 inches tall by 2.8 inches wide, this blender stands taller than most. At 2.9 pounds, it feels pretty heavy in the hand as well — quite the opposite of many other models. The hefty weight is a consequence of its all-stainless-steel construction that is meant to ensure optimal longevity, but we found several competitors, such as the KitchenAid, could be just as durable without the added heft.

Made of medium-quality plastic reinforced with brushed stainless steel, the KOIOS’ body feels relatively solid (but it doesn’t look as sleek as the higher-priced models). Unlike the BELLA 10-speed, it showed no scratches after our course of testing. So far, we haven’t noticed any damage on the exterior; our blender still looks shiny and brand new.

There is a special inner rotary core fixed in the blending shaft that’s different from most immersion blenders in this price range. Thanks to this add-on, the tools are easy to attach to the motor body. Not only that, but they also latch securely in place, unlike the Muller Ultra-Stick that occasionally let go of its whisk.

On the whole, the All-Clad 10942212300 is well-engineered. Its interior is quite refined while the exterior uses high-quality stainless steel. Hard plastics are still present in a few areas, but they look stately and are meant as highlights.

We often feel a bit awkward with blenders that control speed with top-mounted dials; it’s really challenging to move the blending wand, adjust its speed, and hold the beaker at the same time. With the KOIOS, however, that isn’t an issue.

Our 4-in-1 machine offers 12 speed options and a Turbo function. It’s all controlled using two buttons and a dial. While the front controls are extremely responsive, the dial lets us switch between various speed settings with ease and this is partly because the blender itself runs very smoothly.

In particular, throughout each of our tests, we noticed that its motor didn’t vibrate too violently. This helped reduce the overall impact on the beaker and kept it stable rather than constantly jumping around the countertop. In other words, we didn’t need to hold the beaker throughout the whole job, so it wasn’t a problem to dial in the speed with a spare hand.

However, if you find it hard to adjust the dial, you can always just hit the turbo mode. That sends the blender into its highest speed immediately.

Controls used for this blender’s operation include two press-buttons and a speed selection knob. The “TURBO” button will give you a quick burst of power. For more controlled acceleration or deceleration, use the power button and the knob. It may feel like you need an extra hand, though, if you’re constantly stabilizing the blending beaker on the table. Adjusting the All-Clad’s speed can take some practice.

Made of standard stainless steel plated with titanium, the blade has two prongs: one is sharp and the other is dull. Its relatively fragile construction means it isn’t intended for tough ingredients like ice cubes or coffee beans, but it’s still tough enough to handle whole-food combinations.

Unlike most other blenders with lobed or angular guards, this one’s blade guard is shaped like a parabolic arch. This special design allows us to easily reach the blade’s backside for cleaning. The vaulted slope also doesn’t trap food the way others do, so we never had to stop and dislodge debris with a spoon.

The blade guard is also designed to reduce splattering, and it’s really up to the job. However, due to its metal construction and sharp edges, it left marks on the beaker even when we blended very carefully.

Constructed of hardened stainless steel, the 2-prong blade is super sharp and sturdy. Around it is a metal guard designed to minimize food splatter and head suction, but we don’t think this part is up to the task. Not to mention the fact that it will scratch the interior surfaces of your cookware if you don’t blend very carefully.

Ease of Use

7.8

This KOIOS is easier to use than many other blenders not only because of its simple design but also because its buttons are very responsive. The motor’s minimal vibration contributes to the overall usability scores as well. Since the machine itself runs very smoothly, we can maneuver the blender in comfort. It was a pleasant departure after the excessive vibration of some other blenders.

During our testing, we also found that this blender didn’t create suction — a main cause of splattering when you lift it upward for an even blend. As such, we didn’t experience any trouble when speeding up or moving the blending wand, even at the highest speed setting.

During our hands-on testing, we noticed this blender didn’t deliver its power as cleanly as we would prefer. The motor did not accelerate smoothly, causing hand fatigue and making our blending motion more difficult. Plus, the blades splashed food everywhere.

Due to its heavy weight, the All-Clad 10942212300 is a bit fatiguing to use for extended periods. It’s also quite cumbersome to maneuver, especially when you change speeds, since the blender suctions itself very tightly to the beaker. There may be a way to beat the suction without creating a mess, but we haven’t found it. 

The other inconvenience is that food gets lodged in the blade guard’s holes. You may need to pause repeatedly during the blending process to clear them.

8.5

Blade Assembly

8.0
The KOIOS Blade Assembly

This blender comes with accessory ejection buttons on the motor body — a handy add-on giving you more control over the blade detachment process. Just a quick press of these clicky buttons pushes the attachment off of the motor body.

Putting them back is easy as well. Simply align the shaft with the main housing and push until they click and lock into place. There is one thing we really like about this blender’s blade assembly, though: Unlike others, the KOIOS attachments do not need to be rotated to a specific alignment to lock into place.

A simple twist will connect the main body to the blending shaft. But, again, the weight may make that job tricky if your hands are small or greasy.

Handling

8.5
Someone uses two hands to control the KOIOIS immersion blender: one for holding the handle and pressing the power button at the same time, the other for rotating the speed dial.

The handle was comfortable to grip in all of the tests. Together with the machine’s minimal weight, its ergonomic design helps stave off hand fatigue, even through long bouts of vigorous blending. It also helped us maintain a grip even when the surface was wet or covered in grease.

The handle is ergonomically designed to provide a comfortable grip. Not only that, but it also has a rubber grip which is particularly handy when you have sweaty or slippery hands.

8.5

Cleanability

8.0

We found the easiest and most effective way to clean the blending wand or any blending attachment was by scrubbing it under running tap water. More often than not, food tailings could be quickly removed, even when they accumulated in the blade’s backsides.

Cleaning this All-Clad is less of a hassle than most. You can wash it by hand easily or put the blending shaft in the dishwasher. The only things to be careful of are the blade’s backsides — it’s hard to reach under the blade, so a cleaning bottle brush is practically a necessity.  As with any blender, the motor section cannot be immersed in water and should only be wiped down with a damp cloth.
