does the Wahl Professional Peanut Cordless Hair Clipper/Trimmer 8663 shave/buzz heads like an ordinary buzzer?

Absolutely. It works with all the Wahl attachments and guards. And it’s got the rechargeable battery…

I want one of these. Wahl clippers are the best you can buy, they will never go out on you.
