Review (5/5): Works great! Gets the undercoat.
This brush is sturdy. Nice heavy feel. Teeth really grab the undercoat. Within just a few strokes, I had removed enough hair from my cats to form a whole other cat! One of my girls loved it, but the one who usually enjoys being brushed didn't care for it. Not sure what's up with that. It wasn't hurting her, I think maybe since it grabbed so much hair, maybe she didn't like the extra little "tug". There are 2 different curves to the brush and I didn't really notice a difference in the effects. I also tried to rake the rug, which I have done with my usual brush. This was absolutely not working with this one. It grabbed so much it was actually lifting the carpet. This worked on fine cat hair, so I can only imagine how well it would grab the hair and de-shed a dog. I didn't have any use for the added light and strap. I suppose the strap would be useful to hold a dog with a collar in place and the light would be useful for potty trips at night.
