Bests & Worsts Reviews from Amazon

I bought this a few months ago. I wanted to wait to write the review. I wanted to give this product a fair chance. I have a 4 pound yorkie and a 90 pound lab. I tried using this on both my dogs . They did not like it. I started off slow, just letting them smell the grinders and get use to it. The grinder wheel gets hot after 1-2 seconds and make my pups cry out in pain. I do not recommend this product. It is also noisy and uneasy to use . Total waste of money.
