Simple design and advanced convenience features make the Breville BSB510XL Control Grip a great balance of comfort and durability. Overall performance didn’t quite live up to our expectations for a premium immersion blender, but at least, it is capable of blending frozen fruits, emulsifying sauces, and whipping egg whites. 

The KOIOS 4-In-1 isn’t as appealing as the Breville BSB510XL Control Grip, but we think highly of this blender. It shares the same capabilities as the competition but works quicker and more efficiently. Overall, it is a niche immersion blender for people who want something more versatile than a typical one but don't have the budget to get a luxury all-arounder.

Hot Soup Purée

6.5
The KOIOS 4-in-1 Soup
KOIOS 4-In-1 Hot Soup Purée 1
  • Pureeing Time: 30 seconds
  • 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.

Breville BSB510XL Control Grip Hot Soup Purée

  • Pureeing Time: 30 secs
  • Result: Smooth
  • Suction: Slight

The Breville BSB510XL is not a bad choice if you need to create hot soup purées in a hurry. Breaking down cooked veggies into liquid form is this machine’s forte. 

Although our test soup did retain a few unblended chunks, it was acceptably smooth and had a nice creamy consistency even without adding dairy. Our purée test runs for only 30 seconds, though — you will likely get a silkier soup if you blend longer.

7.8

Frozen Fruit Smoothie

5.8
The KOIOS 4-in-1 Smoothie

  • Blending Time: 1 min 20 secs
  • Result: Slightly Coarse
  • 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.

Breville BSB510XL Control Grip Smoothie

  • Blending Time: 2 mins 21 secs
  • Result: Smooth
  • Suction: Slightly

The Breville BSB510XL produced a silky smoothie with almost zero leftover sediment. The task did seem challenging, though, since it took nearly a full minute longer than average. You may not mind a little extra time, but frozen fruit smoothies are actually best when they’re blended quickly; the extra time and blade contact will thaw the ingredients and give the resulting smoothie a more watery texture.

9.8

Mayonnaise

4.8
The KOIOS 4-in-1 Mayonnaise
  • Emulsifying Time: 1 min 10 secs
  • Result: Velvety
  • Suction: No

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.

Breville BSB510XL Control Grip Whipped Egg-Whites
Breville BSB510XL Control Grip Whipped Egg-Whites 1
  • Emulsifying Time: 2 mins 40 secs
  • Result: Quite Thin
  • Suction: No

The Breville BSB510XL took 2 minutes and forty seconds to create a batch of mayonnaise featuring three egg yolks and 240ml oil. This was nearly a minute and a half slower than the fastest immersion blenders we tested (such as the Cuisinart CSB-175 Smart Stick).

The sauce had a pale yellow color. It was light and creamy like pudding — neither great nor bad. It lacked the thick texture we prefer, suggesting that better emulsion would demand more oil.

7.5

Almond Milk

8.5
The KOIOS 4-in-1 Almond Milk
  • Grinding Time: 1 min 10 secs
  • Result: Fine
  • 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.

Breville BSB510XL Control Grip Almond Milk
  • Grinding Time: 56 secs
  • Result: Smooth
  • Suction: Tightly

The Breville BSB510XL performed well in this test. Of all the mid-powered blenders we tested, it was among the select few that pulverized the nuts evenly and drew the most flavor out of the almonds. After we’d removed the pulp with a mesh strainer, it tasted smooth and creamy, too.

7.0

Whipped Egg-Whites

10
The KOIOS 4-in-1 whipped egg-white
  • 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. 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.

  • Beating Time: 1 min 21 sec
  • Result: Stiff
  • Suction: No

The Breville BSB510XL was excellent at beating eggs. It requires less than one and a half minutes to churn out a stiff-peaked whip from 100ml of egg whites, which was considerably faster than most of its peers. If you use this blender to make meringue, you won’t need to make any special preparations; the Breville BSB510XL will readily handle it.

Contributing to the high price tag is a set of well-designed attachments, to include a whisk, a chopping bowl, and a 42-ounce blending jar with dual-purpose lid. All of the attachments are top-rack dishwasher safe, which is definitely a big plus. They’re also very practical and easy to use.

Like all the light-duty immersion blenders we tested, the KOIOS 4-in-1 is well balanced. It is compact, portable, and has a long blending shaft that can be immersed in even a deep pot.

  • Shaft Length:
    9.3" (23.6 cm)

At 16.5 inches, this blender’s length is about average. It is top-heavy, though, so it can feel unstable, especially if you want to rest it against the side of your blending beaker when you pause the motor. On the bright side, that length may allow you to reach the bottom of deep pots more easily. Our other concern is the blade housing’s large size; it won’t fit well in all potential containers.

Build Quality

9.0
KOIOS 4-In-1 Immersion Construction

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.

Breville BSB510XL Control Grip Build Quality

The steeper price of the Breville BSB510XL is justified by its build quality, which is hard to beat. While we have different opinions about the plastic coating of its motor body, whose finish is likely to be marred with minor scratches after repeated use, most everyone agrees that this blender will offer you great durability overall.

The KOIOS’ beaker has a small 20-oz capacity with measurements in both milliliters and fluid ounces. As a nice bonus, it sports a flared base to ensure stability.

The beaker has clearly marked measurements for convenience. It is almost twice the standard size, making it easier for you to maneuver the hand blender around. And since there is more room in the container for the mixture to rise, it also helps to prevent overflow.

For storage, the cup comes with a lid, which then snaps onto the bottom of the cup to keep the container from moving on the countertop when you’re blending. And for some operations, such as making a smoothie, the handle on the jar gave us a good grip.

Speed and Controls

  • Noise Level:
    90 dB
  • Digital Display:
    No
  • Pulse Mode:
    Yes

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.

The motor has 15 speed settings, giving us precise control over our food’s texture. To switch between different speed settings, simply turn the dial at the top of the blender’s motor body. All the controls, including the power button and the speed dial, demand minimal pressure from your finger.  

To blend at high speeds, the manufacturer recommends that you start with the slowest speed and gradually increase to the higher ones to minimize splattering or over-processing. However, we found it difficult to get this job done when both your hands are engaged while blending — one hand to use the controls and the other fighting the blender’s suction force.

  • Blade Count:
    2
  • Removable:
    Yes
  • Dishwasher Safe:
    Yes

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 blending shaft is made of high-quality stainless steel to ensure durability. There is a plastic rim around its base, which is meant to reduce head suction and to protect your cookware from scratches. 

The blade has two prongs—one is razor sharp and the other is dull. To keep the former sharp, you should avoid using it to crush whole ice cubes or to grind raw nuts without liquid.

The power cord is long enough to reach nearby outlets. It’s notably designed with a finger hole in the power plug so you can easily and safely remove it from the wall socket.

Whisk Attachment

Extra Accessories

Whisk Attachment
The KOIOS 4-in-1 Immersion Blender Whisk Attachment
  • Material:
    Stainless steel
  • Dishwasher Safe:
    Yes
  • Removable:
    Yes

This whisk attachment is moderately good at certain tasks like beating egg whites, whipping cream, and making emulsified sauces. Compared with other low-priced hand blenders such as the BELLA 10-speed or the Hamilton, its polished stainless steel wires feel more sturdy and durable under consistent use.

Breville BSB510XL Control Grip Extra Accessories: Whisk Attachment
  • Material:
    Stainless steel
  • Dishwasher Safe:
    Yes
  • Removable:
    Yes

The whisk attachment functions as a hand whisk so you can whip up cream, beat egg whites, and emulsify sauces without a stand-alone mixer. In terms of quality, this part is well built, but one of its wires somehow has a very awkward shape. We can’t say for sure if that happened during shipping or on the production line.

Food Processor

We haven’t conducted tests on this attachment, but the stainless steel S-blade’s construction looks capable of chopping various foods just like any other low-grade food processor.

We haven’t tested this attachment, but we think it could serve you well when making something like basil pesto. It could be a good alternative if you don’t want to bother with a full-sized food processor. The Breville can be a moderate food processor in its own right since the included chopping bowl comes at just the right size for chopping vegetables, onions, and more.

Ease of Use

7.7

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 Breville BSB510XL allowed for a thorough blending process since food didn’t get lodged around the blending blade or in the blade guard. We could get an even blend without having to pause our blender and dislodge trapped chunks. 

Moreover, the motor operated very smoothly so we didn’t need to hold the beaker throughout the whole job to keep it from moving around (as was necessary with certain other blenders such as the Mueller Ultra-Stick). 

After each task, the cleanup was messier than we anticipated, though. This was because the suction force entirely threw off our momentum when we went to draw the blending wand up. The Breville created a lot of splatter every time we moved it around.

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.

The process of assembling your blender is very easy; simply align the top end of the blending attachment with the corresponding end of the motor body and then push until you feel them ‘click’ together. Separating the two pieces is simple as well thanks to the EJECT buttons on either side of the motor body.

8.0

Handling

8.5
The KOIOS Non-Slip Handle

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.

Breville BSB510XL Control Grip Handling

Suctioning problem aside, this blender is among the easiest models to maneuver. You hold the Breville with one finger wrapping over the power trigger rather than just pressing it with a fingertip. Contributing to its comfortable grip is the handle’s rubber coating. Apart from staving off hand fatigue, this feature will help prevent your hands from slipping if they’re wet or covered in grease.

8.5

Cleanability

7.5

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.

With the exception of the motor body, all the pieces are dishwasher-safe. However, we recommend hand washing so as to get the best long-term use.  

While cleaning it manually, we didn’t have to use much elbow grease on food tailings. For the most part, they rinsed off effortlessly under the tap. The only troublesome things were sticky and water-insoluble residues, like mayonnaise, which demanded some scrubbing. Getting that residue off the backsides of the blades was a frustrating process.
