I always fall for the gimicks. When I bought it I didnt know that you have to replace the inside cutting part which just looks like sandpaper. I have used this on my Beagle and she hates it, but it is easier in some ways to use this them the clippers. With clippers I am bad with clipping her Quick. The bad thing about this is that it takes forever to do one nail and odd to position it just right. This only has a small hole opening which I dont like because i also have 3 labrador dogs and their nails are much to large to fit in the small hole. There is a bad smell when you fiel down the nail.
