So far I've only used it to file claws for my 3 dogs (although I have some crafts planned) and it's worked great for that. It's a bit louder than the slower and weaker pet version so I had to spend some time and lots of super tasty treats to get all my dogs to eat, except it's quiet - but it works MUCH faster and better - which I think is fair trade consider . I have dogs that weigh over 100 pounds. so her nails are really thick. I had a pet nail grinder that required grinding for several minutes PER NAIL. I do this weekly and it takes about 2 minutes per dog. I think we are all happy with that.
