Barely adequate is an understatement. I bought a Chef's Choice thinking it would be great for small jobs when I didn't want to break out the 85 pound Berkel. The underwhelming power, the dull serrated blade and the cheap, flimsy, plastic screw that only had a tab that folded out to twist for removal of the blade made me shelve it. I bought it because I thought it would save time for small jobs. Not true. Only plus was the weight and the small size. I eventually gave it to my youngest to slice deer meat for jerky. After a few attempts he shelved it because he says he can partially freeze the meat and slice thinner with a sharp knife.
It's like comparing a brace and bit to a power drill. If it works for you and you're satisfied then you're good to go.
