Who it's for
Suits someone who wants strong ice-crushing and smoothie performance without paying Vitamix pricing, and who does not mind a blender that runs loud during operation. Less suited to anyone who wants total quiet or has been burned before by gear failures in mid-price blenders and wants a longer proven track record.
What buyers say
From Amazon customer reviews.
Owners are impressed with how finely it crushes ice and blends smoothies for the price, with repeated comparisons to Vitamix in its favor. The clearest complaints are the noise level during operation and a main gear that has cracked and stopped the blades for several reviewers within the first year, though Chefman's warranty replacements are reported to use sturdier metal gears.
