Both these models are low-range blenders, but the KOIOIS 4-in-1 somehow managed to churn out smoother results, from smoothie to puree soup to mayonnaise. Another reason why we much prefer and would like to recommend the KOIOIS 4-in-1 over the UTALENT 5-in-1 is its more pleasant user experience with more responsive buttons and a smoother operating motor.

Of course, at under $50, your KOIOIS won’t come with many special features. It is just an average bender that deals with most light-duty tasks without blowing your mind, but given its more efficient performance compared with not only the UTALENT 5-in-1 but also other low-priced blenders we tested, we believe it is your only practical choice in this range.

Hot Soup Purée

  • Pureeing Time: 30 seconds
  • Result: Chunky
  • Suction: Slightly

None of the low-range blenders we tested churned out the silkiest puree in 30 seconds, but the UTALENT’s soup was so chunky that we couldn’t consider it a pass. Most of the unprocessed chunks, including carrots and celery, are large enough to be visible after straining. Some couldn’t even be blended because they got lodged in the blade guard’s holes.

Making hot soup puree is the easiest and most basic task of an immersion blender so it really doesn’t make sense to buy this one.

  • 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.

  • Blending Time: 2 minutes
  • Result: Leafy
  • Suction: Slightly

The UTALENT is definitely not for you if you like your smoothies packed with frozen fruit or green veggies. Apart from being too weak to blend through tough ingredients, it’s also unable to liquify leafy veggies effectively.  

Our smoothie was churned out with a grainy, leafy texture even after up to 2 minutes of processing. Upon stirring it to check its smoothness, we noticed that there were some grains of unprocessed kale still left in the mixture.

Furthermore, the machine required our intervention to draw all the ingredients toward the blades: We had to constantly stir with the blending wand to ensure everything was incorporated. What a frustrating blending process!

  • Suction: No

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.

Our mayo sauce was a very simple one: an emulsion of oil blended with egg yolk. We made it in about 1 minute and a half using the blender’s whisk attachment. Regarding its consistency, we wished that it could have been creamier. Although this machine made short work of incorporating all the ingredients, our emulsification came out relatively thick—albeit stable.

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.

  • Grinding Time: 2 minutes
  • Result: Coarse
  • Suction: Tightly

Of all the blenders we tested, the UTALENT was the slowest performer. It took up to two minutes to complete this task — twice as slow as the winner, the Cuisinart Smart Stick. And even still, the nuts weren’t evenly ground. As a result, our milk couldn’t pack the full flavor of almond. It was drinkable but quite watery and not as creamy as it should have been.

  • 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.

  • Beating Time: 2 mins 50 secs
  • Result: Stiff
  • Suction: No

The low power rating made this blender lag behind its rivals. We had to spend a great deal of time to achieve a stiff peak. Of course, it wasn't a big deal to simply blend for a few more minutes but the prolonged operation caused the motor to overheat, thus impairing its durability. Still, this is a pretty common occurrence for most low-grade blenders. To name a few, the Mueller Ultra-Stick, Hamilton Beach 2-Speed, and the BELLA 10-Speed.

  • 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.

Build Quality

Low-range blenders like this UTALENT are often of a medium quality with a few shortcomings in the design. For the most part, their exteriors are averagely built with a shiny look, but the inner core that connects the blending wand to the main body feels flimsy and lacks durability. This is a serious point with wider implications — if the core breaks, it will render the blender useless. The gasket that helps tighten the main body and the attachments is also substandard. We noticed it became discolored after just five times of use.

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.

Speed and Controls of the Utalent 5-in-1 Immersion Blender

The UTALENT works much like other hand-held blenders sporting multiple speed settings. It allows you to speed up smoothly through the top dial, which doesn't, however, seem to make any apparent difference when it comes to the blended result. That’s why we rarely used this control in our hands-on testing. 

Instead, we often use the Turbo mode located on the front interface— a function that instantly sends the blender into its highest speed. That said, this control, like the power button, demands quite a bit of force from the user.

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.

Blending Shaft

  • Dishwasher Safe:
    Yes

In terms of shape and size, the UTALENT’s blending shaft differs in two ways from other immersion blenders. So far, we haven’t noticed any benefit from this unusual design. Worse still, the shorter length 4-prong blade reduces contact with the blending food, thus leading to an increment of blending time. 

Not only that, but it also cannot tackle heavy-duty tasks. It is too fragile to blend through solid foods like ice cubes or raw root veggies without being damaged or deformed. 

Together with the smaller blades is a narrower blade guard. If food gets lodged, this makes it trickier to scrape the sides to dislodge the food without the blade getting in the way. Entirely made of stainless steel, the blade guard is also a potential risk for your nonstick cookware surface.

    2
  • Removable:

  • Dishwasher Safe:

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.

Ease of Use

8.3

The intuitive interface makes it easy to figure out how this machine works, but it still doesn’t make the blending a pleasant enough experience. Since the blender itself often vacuums to the beaker’s bottom, it may cause excessive splatters when you move your hands. 

In addition, due to the motor’s violent vibration, we couldn’t maneuver the blender comfortably. Our hand muscles had became tired after just two tests, and as a result, we encountered some difficulty in speeding up or moving the blending wand in the subsequent tests.

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.

7.0

Blade Assembly

8.5

Setting up the blender is a straightforward process. Simply align the attachment with the main housing and make a quarter turn counterclockwise until you hear it click into place.

That said, if your hands are wet or oily, the whole body’s polished-plastic exterior can be too slippery for a secure grasp. This challenges the detachment process, especially when this machine lacks an accessory ejection button.

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.

Handling

8.0
Someone is holding the UTALENT’s handle with one hand and at the same time, rotating the speed dial on the top of the motor body with the other hand.

The handle is comfortable and its ergonomic design helps to maintain a secure grip, but the blender's violent shaking still made it difficult to avoid hand fatigue throughout our tests.

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.

6.5

Cleanability

8.5

After each test, we noticed that the blade’s backsides were home to a large amount of residuals that couldn’t be simply rinsed off under the running water tap. And due to the restricted space between the blade and its guard, we couldn’t get our fingers in to remove them. If you want to get a thorough clean, you must use a straw-cleaning brush.

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.
