    7.8/10

These two blenders are competing for different customers. As a battery-powered device, the KitchenAid KHBBV53 is an ideal option for those demanding maximum mobility. The KOIOS 4-in-1, however, must be operated close to a power outlet and is more suitable for budget-focused buyers. 

That difference aside, both the KitchenAid KHBBV53 and the KOIOS 4-in-1 perform averagely when pureeing hot soup, blending frozen fruits, and making mayonnaise. Their usability is also roughly the same. 

Certainly, the choice between the KOIOS 4-in-1 and the KitchenAid KHBBV53 is more about your need for mobility than any other factor.

  • 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.

This stylish hand blender worked quickly and made acceptable puree soup without a struggle. The sharp stainless steel blades allowed it to hot blend root veggies quite uniformly. Even fibrous ingredients like celery and onions ended up fully incorporated into the mixture. 

Although the KitchenAid KHBBV53 didn’t create a perfect puree, our soup looked good and was much silkier than that produced by its competitors, such as the Mueller Ultra Stick and the Hamilton Beach 2-speed.

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.

Featuring multiple speed settings, this KitchenAid KHBBV53 pulverized all the ingredients with ease, which was really surprising. 

The blending process also went as smoothly, though, at certain points, fruits got trapped under the blades, demanding us to stop the machine and dislodge the food. Plus, to achieve an even blend, we had to move the blending wand as constantly and consistently as we could. However, that didn’t make us feel frustrated, especially given that the result was exactly what we’d like — it looked silky and more than appetizing. If you buy this blender, we believe no smoothie recipe could overwhelm it.

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.

As a battery-powered blender, the KitchenAid KHBBV53 didn’t work as quickly as its corded counterparts. In fact, it was about 50% slower than the fastest Cuisinart Smart Stick even though it sells for nearly double the price. 

On the bright side, the KitchenAid produced acceptable mayonnaise. Although the sauce didn’t look as creamy as we’d like, its smooth and fluffy texture would be enough for any salad.

  • Suction: No

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: 50 secs
  • Result: Coarse
  • Suction: No

The KitchenAid KHBBV53 is adequate for preparing non-dairy milk, but isn’t deserving of much praise. Of all the blenders we tested, this was the only one that created a foamy texture as a result of too much incorporated air. We removed the foam during the straining process so it didn’t impair the milk’s quality in the end. But it’s worth noting that the milk would have overflowed onto the countertop if we hadn’t paused periodically to stir it back into the jar with a long spoon. 

Moreover, this blender didn’t blend as evenly or as consistently as its mid-range counterparts, namely the Braun MultiQuick-5. Consequently, our milk didn’t get all the flavor out of the almonds. It was still an acceptable alternative to store-bought almond milk, but not ideal.

  • Beating Time: 2 min 40 secs
  • Result: Stiff
  • 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.

The KitchenAid KHBBV53 was doomed to failure in this test since there was no way its blending wand could draw enough air into the egg-whites to form them properly. As a result, it left us with a cloudy cup of two separate layers: bubbly film and eggy water. Other blenders with whisking attachments, on the other hand, achieved stiff peaks quite easily.

Build Quality

8.5

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.

The KitchenAid KHBBV53 is quite an expensive blender, so we’re happy to say its solid construction delivers on that price tag. As a mid-range blender, it doesn’t look as sleek as the premium ones (for example, the Vitamix 5-speed), but this doesn’t mean it’s less durable. Although it is mostly made of plastic, it seems to be high quality and the metal parts resist corrosion pretty well. So far, we haven't noticed any damage on the exterior, even though discoloration is fairly common among immersion blenders with plastic components.

The blending shaft, on the other hand, leaves a bit to be desired. Its blade guard is made of stainless steel but looks relatively flimsy and doesn’t have a good finish. It is flecked with countless black spots which can’t be wiped off. That certainly ruins the interior’s shine but doesn’t impair operation.

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.

This blender offers multiple speed options and its trigger switch is extremely responsive. In a departure from most, the speed is determined by the amount of pressure you apply to the trigger. Your blender will run at its highest speed if you press the controller all the way down.

There is also a palm switch on the blender’s backside which acts as a safety mechanism. To blend, you must hold that switch down along with the trigger switch. We personally appreciate that idea since it helps prevent the motor from being accidentally engaged and hurting someone.

Although the KitchenAid KHBBV53 doesn’t feature a separate switch for a pulse function, you can also get plenty of control over your chopping preparations by pressing the trigger in short bursts.

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.

The KitchenAid KHBBV53 features two-pronged blades which can withstand consistent use pretty well but don’t look as impressive as the higher-priced counterparts, such as the Vitamix.

Blending with this blender is a pleasure since its blade housing helps limit the splattering. Although the guard is made of metal, it won’t leave scratches on your cookware’s interior if you attach the included plastic pan guard. In our initial soup test, we immersed our blender — with that pan guard attached — into a glass pot and noticed zero damage.

Ease of Use

7.9

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.

The KitchenAid KHBBV53 is intuitive to use but maneuvering it isn’t as easy. More often than not, we had a hard time with our blending motions since this machine created a bit too much suction. Every time it sucked tight to the blending container’s bottom, we would hardly stir or draw it up without causing a mess. 

Additionally, it took us a bit of practice to be proficient at using the speed controller. To hit the maximum speed, we simply press the switch all the way down, but things are complicated when you want a mid-range speed.  

Not only that, but we also felt quite apprehensive trying to figure out how to speed up or slow down on our own. The user manual doesn’t provide any instructions for that. It even doesn’t explain that the speed trigger switch is pressure sensitive.

8.5

Blade Assembly

7.5
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.

We set up our blender by aligning the blending wand to the motor body until they locked in place. To disassemble, we turned the attachment counterclockwise and then pulled it out from the body. That sounds as easy as one-two-three, but since this blender doesn’t include a release button like most others, removal demands more pulling force, which may be trickier to do if your hands are oily.

8.0

Handling

7.5
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.

Someone holding the KitchenAid KHBBV53 Handle and pressing the speed controller at the same time.

This blender is comfortable to hold thanks to the ergonomically-designed handle, but the slick, polished finish will be slippery when it’s oily or wet. This can make your grip unstable, especially if your hands fatigue quickly.

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.

The blending wand is dishwasher-safe, so cleaning will not be a challenging task. However, if you clean it manually, getting the blades’ backsides to sparkle again is almost impossible without a bottle-cleaning brush.

Following each test, we used a soapy sponge to scrub away the food tailings and most of the residue rinsed off easily. However, we couldn’t simply wipe away all sticky remnants (like mayonnaise) that clung stubbornly in the back of the blades. Instead, we had to use a straw-cleaning brush to get into those hard-to-reach spaces.
