The Muller’s motor is 500 watts, which is notably powerful but shouldn’t be used for pulverizing solid ingredients like coffee beans or whole ice cubes. To prevent damage, you shouldn’t operate it continuously for longer than a minute, either, though it’s designed to shut off automatically and will reactivate after cooling if becoming excessively hot.
We like the look of this blender, especially the color-coded LED ring on top. It lights up during operation to create a fancy blending experience. The overall quality is fine with all parts coming as standard. However, we did have a few reservations about the blades’ metal housing, which presents some shortcomings that you may feel uncomfortable with.
Regardless of the inexpensive price, we suppose this blender may be less appealing to some users – particularly those demanding high durability or with wrist injuries.
The Chefman’s usability is great. There’s no cord to accidentally yank on, allowing for maximum flexibility while blending. With the balanced size, it isn’t cumbersome, creating a comfortable experience even when you're pureeing a large batch.
The Muller didn’t give us superior blends in all the tests. It wasn’t powerful enough to break down large chunks of fruit and veggies, even when we had cut the solid ingredients into smaller pieces before blending. For the most part, however, its blended results were acceptable.
The Chefman is a moderately capable blender. With stable battery power, it brings quite a lot to the table. In our tests, it didn’t work particularly quickly, nor were the results among the best, but based on its testing performance, we’re confident that the capabilities of this blender extend beyond soup, smoothies, and mayonnaise.

With the exception of the hot soup test, these two immersion blenders shared the same performance quality. For the soup test, the Chefman Cordless churned out a smooth batch of puree in only 30 seconds. In the same time frame, meanwhile, the Mueller Ultra-Stick left us with a lot of unprocessed chunks.
The Chefman's materials are of a higher quality, nullifying the cheaply plastic feel of the Mueller Ultra-Stick. Its design also feels more refined overall. In terms of usability, the Chefman Cordless is more reliable to use. It works more simply, portably, and conveniently, too.
If you simply want an immersion blender for basic tasks, the Mueller Ultra-Stick is not a bad choice, and it offers a few capabilities that are not present in the competition thanks to the extra whisk attachment. However, for a few extra pennies, the Chefman Cordless will make a difference.
