Having 2 dogs, I have found it nearly impossible to clip their nails. I've tried different clippers, battery operated files, nothing worked. The clippers would split my dogs nails, and the battery files...not even worth the price tag as both were afraid of it. These clippers are amazing! My little dog, which is the hardest to do, sat on my lap and I clipped away. It took me literally 10 seconds to do both front paws. Each one clipped perfectly. The clippers even have a guard on them so I can't cut down to the quick by accident. All nails were clipped without any peeling or cracking. This is the first time I was able to do his nails without having to take him to the vet to do it in over a year!!! These are very high quality and safe. I highly recommend to any pet owner!!!!
