I bought one about 4 months ago. It does take a bit to get them used to it but if you take it slow they will do fine. I found that it doesn't do well if you let the nails get too long because it takes too long and they don't don't want to hold still that long. So if they are too long I cut them first and use the peticure to file the sharpness down. They do like it better than the nail cutters, even my little 3 pounder who is a real baby. It takes two of us to cut her nails but I can do the peticure on her by myself. Yes you do need to be careful if the hair is too long so trim that first. I would recommend buying it even if just to file the sharpness away so you don't get scratched by
the sharp newly cut nails.
