KOIOS 4-In-1 Immersion vs Hamilton Beach 59765 Immersion Side-by-Side Comparison
Our Verdict
- Performance (50%)5.7/10
- Design (20%)6.0/10
- Usability (30%)6.4/10
- Performance (50%)7.9/10
- Design (20%)7.6/10
- Usability (30%)8.3/10
The KOIOS 4-In-1’s performance could be best described as fine but unremarkable, passing all of its tests with acceptable results. However, compared with the Hamilton Beach 59765, it created a more pleasant yet powerful blending experience without any violent shaking or a loud motor.
Of all the low-range immersion blenders we’ve experienced, it was actually the most efficient one. In certain tests, its results were even smoother than those of higher-priced blenders, such as the Cuisinart.
Equally important, it is easier to use and clean than the Hamilton Beach 59765. We didn’t have to get used to it, and more often than not, any food residuals were rinsed off easily with soapy water.

Hot Soup Purée
- Pureeing Time: 30 seconds
- Result: Smooth
- Suction: Slightly
In this test, the Hamilton Beach produced an acceptably smooth puree, but the outcome wasn’t any better than those produced by other immersion blenders we’ve found for under $40. It was blended evenly but we still noticed a lot of tiny veggie chunks left behind after straining.
- 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. Just in case you’re expecting for silky, restaurant-quality pureés, we recommend the Vitamix 5-speed.
Frozen Fruit Smoothie
- Blending Time: 2 mins 15 secs
- Result: Chunky and Leafy
- Suction: Slightly
Of all the blenders we tested, this Hamilton Beach took the longest to complete this task. It was such a poor performer that had a very hard time processing frozen fruits and couldn’t entirely liquefy kale. In the end, we were left behind with a lumpy icy drink and worse still, a bunch of large noticeable fibrous pieces remained unprocessed.
- 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.
Mayonnaise
- Emulsifying Time: N/A
- Result: N/A
- Suction: N/A
Making mayonnaise with this blender’s whisk attachment was a total failure. Even when we added the oil very slowly to the yolks, there was no way that the blender could form a proper emulsion. Instead of a smooth spread, we ended up with a watery mess. As such, we awarded it no points for this test.
- 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.
Almond Milk
- Grinding Time: 1 min 40 secs
- Result: Coarse
- Suction: Tightly
Using this Hamilton Beach to make nut milk may not be such a good idea: In our test, it left us with a coarse grind and couldn’t pull all the ingredients into its blades without our intervention. That’s why we had to constantly stir with the blending wand to ensure everything was incorporated. This also meant that, due to the machine’s poor head suction, we would end up getting splattered with smoothie every single time our hand moved.
At certain points, the almonds somehow even got stuck in the blade guard’s holes, requiring us to stop and dislodge them. This remains the most frustrating blending experience that we’ve ever had.
- 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.
Whipped Egg-Whites
- Beating Time: 3 min 22 secs
- Result: Stiff
- Suction: No
Surprisingly, this blender’s whisk attachment did a good job of stiffening the egg white. When beating, it provided enough force to stretch out the egg’s proteins which then bonded with each other and formed a stable network around the tiny air bubbles created through the beating action.
However, strengthening that network for a good stiff peak can be a lengthy process. The Hamilton Beach took more than one minute - compared with others, that's longer than the average. Having to spend a few more minutes blending is no big deal, but the prolonged operation will cause the motor to overheat, thus impairing its durability and your cooking enjoyment.
- 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.

In addition to a blending wand, this blender also comes with a beaker, a whisk attachment, and a food processor to enhance its versatility.
Dimensions
- Height:14.3" (36.3 cm)
- Width:2.6" (6.6 cm)
- Weight:1.7 lbs (0.8 kg)
- Shaft Length:6.9" (17.5 cm)
This Hamilton Beach looks compact on our counter and takes up less space than any of the full-sized blenders we’ve had. Its blending shaft and main motor body can be separated so you can easily store them when not in use. It also feels balanced in our hands with an ideal weight for most home cooks. For the most part, we agree it is quite easy to maneuver this machine in a mixing beaker.
- Height:15.3" (38.9 cm)
- Width:2.1" (5.3 cm)
- Weight:3.4 lbs (1.5 kg)
- Shaft Length:7.9" (20.1 cm)
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.
Build Quality
Compared to other low-range blenders we purchased, this Hamilton Beach is similar in features, operation, and capabilities, but it isn’t as good on every front due to its poorly-built construction.
Made of low-range plastic, the motor body takes on food stains and discoloration over time while the inner core is very breakable. The two thin plastic tabs that help connect the blending attachment to the main housing also leave much to be desired. With use, they will possibly snap, thus rendering your blender useless. Another word of caution: this machine has a tendency to overheat like it is burning up.
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 Hamilton Beach 2-Speed Hand Blender
- Control Type:Press-button & speed dial
- Min Speed:15,680 RPM
- Max Speed:17,330 RPM
- Presets:No
- Noise Level:96 dB
- Digital Display:No
- Pulse Mode:Yes
The machine has two buttons: the power button operates the blender at the normal speed and the turbo button provides a temporary speed boost. Both buttons are unresponsive to gentle presses requiring considerable pressure to be activated. During the more prolonged procedures, we experienced challenging and painful blending.
- Control Type:Press-button & speed dial
- Min Speed:11,500 RPM
- Max Speed:14,480 RPM
- Presets:No
- 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.
Blending Shaft
- Material:Stainless steel
- Type:Sharp Blade
- Guard Material:Stainless steel
- Blade Count:2
- Removable:Yes
- Dishwasher Safe:Yes
At only 6.9 inches, the blending shaft is quite short and may not be suitable to immerse in your deep pot. With a sharp, metal blade guard, it seriously damaged our beaker and was incapable of reducing head suction in all of its tests. The 2-pronged blade is designed flimsily. It looks inferior and has a shorter length compared to other low-range blenders. This results in quite coarse blends and longer working time.
- Material:Stainless steel
- Type:Sharp Blade
- Guard Material:Stainless steel
- 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 power cord is long enough that you won’t feel constrained. It has a small loop that is meant to keep the blender organized.
Extra Accessories
- Material:Stainless steel
- Dishwasher Safe:Yes
- Removable:Yes
After two rounds of testing, we found this attachment is completely inefficient. Measuring only 4.3 inches long, it is comparatively short and its wires are too stiff to provide enough ‘bounce’. We certainly wouldn't recommend using this whisk.
- 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.
Extra Accessories
- Material:Plastic and Stainless steel
- Dishwasher Safe:Yes
- Removable:Yes
We haven’t tested this attachment on a specific recipe, but upon activating it without any contents, we found it to be laced with excessive rattles and vibrations, which fatigued our hands over time.
- Material:Plastic and Stainless steel
- Dishwasher Safe:Yes
- Removable:Yes
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.

Ease of Use
The Hamilton Beach 59765 is not easy to use; it often feels a bit brittle during even simple tasks, and that isn’t indicative of all low-priced immersion blenders. It is also more of a pain to use with a violent shaking motor and unresponsive controls.
Furthermore, we found our machine got extremely hot when it was working at high speeds toward an extended blending time. It is unclear if this issue is likely to shorten the blender’s lifespan, but it will surely bring you a
few minutes of discomfort.
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.
Blade Assembly
To set up this blender, the attachment must be rotated to a specific alignment to lock into place with the main housing. So far, we haven't found any difficulty in doing so, since both these two pieces are clearly marked with padlock icons, eliminating our guesswork for the correct alignment.
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
Compared with others, this handle is smaller and less comfortable to hold. While it fits okay in our small hands, it cannot ensure a stable, secure grip due to its slippery surface.
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.
Cleanability
Removing all the food tailings from the blades’ backsides was pretty frustrating. Due to the restricted space between the blade and its guard, we couldn’t get our fingers in for scrubbing.
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.
