JW Pet Company Palm Nail Grinder for Dogs - Quiet Electric Dog Nail Trimmer with Diamond Bit Grinder for Small & Large Breeds - Perfect for Home Grooming & Professional Use

I like the size of the unit overall. As it fits good in the hand! It is not to loud, as to not scar your pet so much.I think it could use a more aggressive grit on the stone wheel. As it takes a long time to get any results on each nail. The batteries are hard to put in the compartment, not user friendly. Removal, I can see will be a whole other issue. The battery cover has a small tip Philip head screw to hold it closed. I think this is overkill, as a slide and click type cover would do just fine. The speed is good, but is easily slowed down by any excessive pressure. Again if the grit was bigger to be more aggressive than it is. I think it would be a more efficient tool. I found it took along time to get done with each nail. And my pet lost all patience, before I could finish even the first paw!
