My girlfriend has a maine coon cat so it has long hair, and a lot of it. We had seen furminators in the store but they were like 30-50 dollars and that is ridiculous for a brush. We had heard that it really worked, but was skeptical. Finally, I saw this one for 15 and thought why not try it. Got it and tried it. AMAZING. I have never seen so much hair come off an animal. That is a double edged sword. SO much hair comes out that if you are not prepared, it gets everywhere. I would also recommend using two people to control the animal and keep it from eating the hair or use a vacuum while using the brush. But great for removing hair. Also noticed that it is kinda sharp and if you do it too hard it can scratch the animal, so be gentle and you will never worry about shedding again. (I am allergic so this gives me peace of mind when I go over there)
