Rivals My Pet Dremel File!
Worked well for me without overheating.  I used this on my husbands thick toe nails to thin them out and stop splitting.  Worked great but be careful not to stay in one spot for too long, as it generates heat on the nail quickly! Still a bit too noisy for use on  my skittish little puppy's nails.  He runs! Hopefully in the future he will warm up to it.  I'm using the pet Dremel for now on the low setting.  I originally started to use it for my husbands nails as well, which is what led me to this one.  This nail file is easier to hold since its slimmer, and it also has a wider range of speed settings. Another great feature is that it works with the same system of tips as the Dremel, so they are somewhat interchangeable. The tips it comes with have a skinnier post than typical Dremel ones do, so you can only use these tips on your Dremel BUT NOT your Dremel tips on this machine!  I like it better than the Dremel though, just hope it holds up well.  You can't beat it for $8.  I just saw one in Bed Bath and Beyond for $20 which clearly is not as good of quality as this one which also was battery powered.  This one uses a cord, which I prefer.
