Good (used once), because I use it for a medium-sized dog, I would maybe like the file point to be a little more "aggressive" (but it does the job with a little patience) and the dog seemed to prefer it (better than cutting).

For the price of 21.80 from 29 and something, it's worth it. It took me about 15 minutes for a cocoon and it held up naturally. It does the job, I just wish it had double the speed so I could have finished much faster. Anyway, it did its job. Now, how long will the batteries (2 AA) last? Have something like a sheet because it rubs the nails and becomes like flour. Patience and you can file from both sides depending on the nails, for example, one is a little flat compared to the others, I put it in the open position so that the wheel passes through it while others in the small slot. You can see how it takes out the nail.
