The two are average-performing immersion blenders with no standout capability, but if you require something more efficient, the Mueller Ultra-Stick has a little bit more to offer. The Chefman 6-in-1 is not a bad choice, but in our tests, its end products were mostly not as smooth, nor as quick, as those of the competition. 

We were really impressed with their extra blending attachments. It’s nice to have such niceties for the price. However, it’d be better if they focused on quality over quantity. Their overall constructions still leave a lot of room for improvement. They are built well enough to get the job done, but at the same time, they’re somewhat flimsy and do not look as sleek as you may expect.

Hot Soup Purée

5.0
Mueller Ultra-Stick Hot Soup

  • Pureeing Time: 30 seconds
  • Result: Slightly chunky
  • Suction: Tightly

Despite being a low-priced blender, the Mueller Ultra-Stick wasn’t any slower than the others we tested. It took about 30 seconds to yield two servings of pureed soup packed with carrots, pumpkin, and parsley.

That said, it wasn’t so good at drawing ingredients toward its blades, so we needed to move it around for an even blend. Moreover, it sucked tightly to the pot’s bottom, which didn’t cause as much spatter as the Cuisinart, but did cause small scratch marks on our cookware’s surface. It also made it very challenging for us to stir with the blending wand.

Our Mueller soup’s texture was acceptable but not the silkiest; there were still several large chunks of veggies left behind.

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

We allowed the Chefman 6-in-1 30 seconds worth of runtime for this test and found that it worked just slightly above average for making a purée of root veggies. Our pumpkins and carrots were blended evenly so the soup came out creamy enough to satisfy us. That said, a smattering of celery fibers still remained unprocessed, making the soup coarser than a restaurant-style dish. It might create a smoother texture with more blending time, so this blender is not a bad choice overall.

Frozen Fruit Smoothie

5.0
The Mueller Ultra-Stick Smoothie Test
Mueller Ultra-Stick Smoothie 1
  • Blending Time: 1 min 15 secs
  • Result: Chunky
  • Suction: Slightly

To ensure this portable machine can do the work of a full-sized blender for making smoothies, we designed this specific test for it. We would award it corresponding points if it could create a homogeneous mixture of just kale and frozen fruit. Disappointingly, we found that the Mueller Ultra-Stick isn’t great at blending solid fruit and leafy vegetables. 

In this task, it had a very hard time breaking up the ingredients. This caused it to demand up to 1 min 15 secs to finish the test. 

And although the Turbo mode is intended to give the blender ​​an extra boost at max speed, we noticed the speed increment wasn’t enough to make any difference. Our smoothie came out pretty smooth, but there were many unprocessed chunks of mango. It was also a bit grainy due to a mass of tiny leafy bits.

As this blender shouldn’t run for longer than 60 seconds at the time to avoid damage, we took a break after 30 seconds. In the meantime, we used a spatula to dislodge the food that lodged in the blade guard.

  • Blending Time: 2 mins 30 secs
  • Result: Smooth
  • Suction: Slightly

We were skeptical whether this blender had enough power to churn through solid ingredients like frozen fruits. In the end, however, it did surprisingly well. It was hard not to notice tiny flakes of kale in the final result, but most of us agree that they didn’t harm the smoothie’s texture.

The trade off was blending time. While sporting the same motor power as its counterparts, such as the Braun MutiQuick-5 or the BELLA 10-Speed, the Chefman  6-in-1 somehow took a full minute more to create equivalent results. Blenders that work faster create a creamier texture because the icy fruit doesn’t have a chance to thaw. The Chefman’s smoothie tasted more diluted.

8.5

Mayonnaise

9.0
The Mueller Ultra-Stick Mayonnaise Test

  • Emulsifying Time: 1 mins 45 secs
  • Result: Smooth
  • Suction: No

Although the Mueller’s whisk attachment has thin, floppy wires, it got the job done in less than two minutes. That was 10 seconds faster than the Braun, whose whisk is more sturdy and springy. It was nearly as fast as the high-end Vitamix and handily beat the cordless KitchenAid by a full minute. 

It was also easier to clean. For the most part, its mayonnaise tailings rinsed off easily under our running tap. Using the blending shafts, on the other hand, caused the food to get clogged in the blade housing. As such, it was very challenging for us to scrub off the residuals on the blade’s backsides.

  • Emulsifying Time: 1 min 30 secs
  • Result: Smooth
  • Suction: Yes

For this test, we combined three egg yolks with 240ml canola oil. This blender took a minute and a half to turn it into pleasant yellowish mayo which had a creamy, fluffy texture that would work well in a variety of dishes. All in all, using the Chefman 6-in-1 to make mayonnaise is a quick-and-easy process, and the same should be true for any other emulsified sauces.

7.5

Almond Milk

5.0
  • Grinding Time: 1 mins 5 secs
  • Result: Coarse
  • Suction: Tightly

Grinding raw nuts shouldn’t be a challenging task for any hand blender. However, our Mueller couldn’t perform any worse, though part of the reason is due to our blending jar — its small size caused the liquid to overflow all over the countertop every single time we moved the blender. So if you intend to use this blender to prepare watery drinks, it’s best to use a bigger container. 

None of the blenders we tested could avoid suction, but the Mueller’s was so strong that it was hard to stir or withdraw the wand, and when we lifted it up the container came with it. These things caused the liquid to easily overflow.

Not only that, but this blender didn’t grind finely enough for a creamy drink. Our almond milk was drinkable, but quite watery and not as sweet as others.

Chefman Vegetable Slicer 6-in-1 Immersion Blender Almond Milk
  • Grinding Time: 1 min 50 secs
  • Result: Coarse
  • Suction: Tightly

The Chefman 6-in-1 created a serving of non-dairy milk in nearly two minutes. It didn’t blend as finely as some other blenders, such as the Chefman Cordless, so the drink it produced was neither the creamiest nor the richest in almond flavor. Nevertheless, this blender can still get the job done and help you skip store-bought versions. It’s always nice to set yourself up for fresher alternatives right at home.

Whipped Egg-Whites

  • Beating Time: 2 mins 37 secs
  • Result: Stiff
  • Suction: No

Before we began this test, we presumed that all the whisk attachments would perform well at  beating egg-whites, though some may be more efficient than others. Surprisingly, Mueller's performance proved us wrong. 

First, it had an advantage over the blending wand in incorporating enough air into the egg whites, allowing the egg-protein to form a stiff, airy foam. What was until its motor seriously overheated several times, requiring us to let it stop and cool down. This issue didn’t regularly occur with the other blenders, and spending so long with the Mueller was tiring. 

Even worse, after this test the whisk attachment had lost its original bulbous shape. The strands of looped wire were all out of their initial order, which would impair its performance in the next emulsifying and beating tasks.

  • Beating Time: 1 min 30 secs
  • Result: Stiff
  • Suction: No

Our eggs turned into an airy, fluffy foam that was stiff enough to stick to the bowl’s sides. Even when we turned the foam upside down, it didn’t fall out. Indeed, this blender’s whisk attachment made meringue a simple and fun exercise.

  • Shaft Length:
    7.7" (19.6 cm)

The Mueller Ultra-Stick has a balanced weight that makes it feel good to use. Since its blending shaft is long enough to reach the bottom of even deep pots, making hot puree soups is pretty much exactly what this machine is designed for. With this compact design, it is also very easy to tuck away in your cabinet when not in use.

The Mueller Ultra-Stick Immersion Blender Construction

The Mueller Ultra-Stick is mostly made of plastic reinforced with brushed stainless steel, so there is no chance of plastic’s chemicals leaching into your food. Besides being corrosion-resistant, this blender’s unique design gives it an elegant look, though it doesn’t feel as sleek as its higher-priced peers.

The blender has two buttons and a speed control knob. All seem straightforward to use, but are cheaply made. To reduce spatter-related issues, the blades are surrounded by a metal guard. We like this idea, but in our experience, this type of guard can scratch non-stick cookware.

Chefman Vegetable Slicer 6-in-1 Immersion Blender Build Quality

The Chefman 6-in-1’s medium-grade construction may not impress you, but we assure it is durable enough for regular use. The blending attachments all attach securely to the motor body, so they’re unlikely to separate while in operation. Like us, you may not like the metal blade housing which will easily scratch your cookware’s surface. For better or worse, though, it's a common feature to help avoid food splatter.

The blades come relatively sharp, but they look flimsy and may dull under regular use, causing the machine to blend less efficiently. Our Mueller’s blades even slightly deformed after the frozen smoothie test.

The blending shaft is sensibly built with a two-prong blade assembly. The blades look sturdy, but their metal housing somehow wound up with several black dots after our rigorous testing procedure. The blade housing is meant to keep splashing to a minimum, but it has room for improvement. It still allowed some liquid to squirt through the openings on the sides.

The power cord has a reasonable length so you can easily plug it into any nearby outlet. We like its small loop as this add-on allows us to hang the whole blender on a hook for easy storage.

Whisk Attachment

With the whisk attachment, your blender can be a nice replacement for a hand mixer for certain tasks, such as whipping cream, beating egg whites, and emulsifying sauces. That being said, we don’t think this additional tool can ensure high durability, given its poorly-built quality.

We haven’t performed any test on the milk frother, but we’re quite sure this attachment can make foam for your drinks. However, we suppose it will not live up to the expectations of serious latté lovers.

  • Material:
    Plastic and stainless steel
  • Dishwasher Safe:

  • Removable:

We haven't performed any tests on the chopper attachment, so we can't say for sure how well it works. Considering the blender’s power rating, however, it should be capable of chopping small quantities of fresh veggies or raw nuts.

The Mueller Ultra-Stick has an intuitive interface, with two buttons and an easy-to-rotate speed control knob. During operation, you can adjust the speed in eight increments by gently rotating the speed control knob. However, as we found out during our testing, there is barely a difference between the Turbo mode and the highest speed in terms of power.

Ease of Use

7.6

It didn’t take long for us to figure out how this blender worked. That being said, the buttons have a very awkward clicky feel. Although they’re not too stiff and demand just a light press to activate, we weren’t entirely comfortable pressing them all the way down. If you use them continuously for more than a batch, your fingertips may feel a bit tired. 

The control knob also makes the blender more complicated to use. It’s tough for one person to use the blender, adjust its speed, and hold the beaker at the same time, so we had to stop it to speed up or slow down.

This Chefman is perfectly comfortable to use one-handed. The buttons are relatively stiff, but they’re responsive and do give us a good sense of control. 

In our tests, this blender acted like a vacuum at the bottom of the beaker, so we got some splatter whenever we moved it around. If the container’s sides were tall enough, though, our blending experience would have been notably better. 

Food tends to cling to the blade guard’s holes. As a result, you’ll probably need to use a food scraper to clean it up every now and then.

Blade Assembly

9.0

To attach the blending wand or any blending accessories to the main body, simply line up the parts and make a quarter turn counterclockwise until you hear the unit click into place.

There is a plastic coupler that attaches the removal parts to the motor body. So far, we haven’t found any issue with this add-on. After spending several days going through hundreds of customer reviews, however, we were warned that the coupler can easily be irreparably broken.

The Chefman 6-in-1 features a simple locking mechanism so blending attachments are very easy to attach or remove. To connect them, you simply insert the motor body into the attachment, then twist until the two units click together.

Handling

7.5
The Mueller Ultra-Stick Blade Handling

We appreciate that the Mueller is designed with an ergonomic handle to reduce hand and wrist pain. However, because the blender itself vibrated pretty violently in all five tests, our hands got tired anyway.

Chefman Vegetable Slicer 6-in-1 Immersion Blender Handling

The handle doesn’t have a grippy silicon layer like some, but it is ergonomically designed to ensure a comfortable grip, which eases hand fatigue while you’re blending. We can’t call this Chefman the most practical blender out there, but it shouldn’t cause problems.

8.5

Cleanability

8.5

All the removable attachments are dishwasher-safe, but we recommend you wash them by hand to prevent their finish from discoloring due to abrasive dishwasher detergents. Thankfully, the manual cleaning process isn’t so difficult.

You can either scrub off the residue under the running tap or let the machine clean itself by blending it in a mixture of dish soap and water. Either method should get it perfectly clean.

All the pieces are safe to put in the dishwasher except for the motor body. Unless you’re short on time, however, you’ll want to wash them manually — they’ll last longer that way. 

We cleaned the blending wand and the whisk attachment by hand and appreciated how easily food tailings wiped away. The only inconveniences were the blades’ backsides which we found quite difficult to get our hands into; you will need a bottle brush to simplify cleanup.
