I cannot believe how well this works. I've been using another for years and I thought it was time to get one with a light so I didn't have to hold a flashlight with my mouth to groom my dog's nails. I'm so glad I chose this one. It's super quiet. The light is perfectly placed. And it grinds so fast I'm getting done in about 1/4 the time it used to take me, which, of course, my dog appreciates. BUY THIS. You will NOT be sorry.
