i have had one of these for about 2 years and use it for my beagle/schnauzer mix dogs (1 boy 1 girl) and while they don't like it they tolerate it ok. it leaves the nails so much smoother than clipping alone. i mostly use it after i clip their nails so they are smooth and don't scratch my floors or legs etc when they tend to jump on me and run on my floors. i just got a teacup poodle and plan to try it on her too. the only reason i didn't give it 5 stars it the cord is a pain in this day of everything being cordless. but it it do-able. occasionally the bands do slip, but from what i read they can do that on all of these type nail products. all in all i would buy this again, but wish it was cordless. oh, and it is not too loud. it gets louder on higher speeds, and you have to be careful with this type of thing not to let it get to hot on their nails.
