Candure, better than the Heusom
I purchased the Candure Dog Nail Grinder, it has upto 7-Speeds, Dog Nail Trimmer for Large, Medium, Small Dogs, Cats & Pets - very Low Noise, a lot quieter than the Heusom silent pro, and cuts 10 times better too.
It also has 3 brightness of led lights on it to so you can see what you're doing.
