The dremel does make noise, but it's not bad at all. It's a quiet hum.

Like all grooming, it's something you have to train a bit at first. But, seriously, after your first 3 Dremels, you become a pro.

Peticure is the same as Dremel, except you can change drill heads and use the Dremel for both wood AND doggy projects Plus, I personally don't like the guard on the Peticure. I prefer to file all sides of the nail rather than just the front. That's how you can really shave it down to small nubs (for visuals of what I mean, check out DoberDawn's tutorial on Dremels).
