I have used these clippers for years and they are the easiest and best I've used. I like that they haven't raised their price in the many years. They also are more reliable and stay sharper than other brands I've also used. Over the years I see a new product so try it out, and every time I come back to these clippers. I use them on small dogs, medium and large dogs. I love the guard so you don't cut the quick of the dog.
