The KitchenAid KHBBV53 is a top-tier contender in the mid-range class. And as with any battery-powered machine, it offers greater convenience than its corded counterparts. 

Besides delivering greater mobility, this cordless blender also blends more evenly than the UTALENT 5-in-1. It can churn through solid ingredients, like frozen fruit, without too much trouble. 

However, despite being less efficient than the KitchenAid, the UTALENT 5-in-1 being corded does eliminate the risk of losing power during blending.

  • 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: Slightly

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.

  • 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!

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.

  • Emulsifying Time: 1 min 35 secs
  • Result: Thick
  • Suction: No

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.

  • Emulsifying Time: 1 mins 54 secs
  • Result: Quite thin
  • Suction: No

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.

UTALENT 5-In-1 Immersion Almond Milk Test
  • 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.

  • 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 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.

The blending wand of the KitchenAid KHBBV53 is immersed in a plastic beaker on a white table containing its failed beaten egg-white.

  • Result: N/A
  • Suction: N/A

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

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.

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.

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.

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.

Blending Shaft

  • Guard Material:
    Stainless steel
  • Blade Count:
    4
  • Removable:

  • 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.

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

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.

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.

Blade Assembly

7.5

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.

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.

Handling

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.

6.5

Cleanability

8.0

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.

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.
