Review (5/5): Dog nail filer, cheaper replacement heads
Used for dog nail filing. It does not have enough power to be any more harmful than normal electric pet nail files. Can be easily stopped with a finger. I put a saw blade attachment and it has a lot of trouble cutting through cardboard. USB recharge is nice to have and skip needing batteries for grooming.
Simple to use and operate. Super for beginners and small jobs that need less power.
