Might be great... if it would stay on the wall
I have three indoor kitties and love the idea of this. However, the bracket that holds the comb is flexible plastic and would not stick to the double-sided tape included to attach the bracket to the wall. The kitties loved the feel of the combs when I ran them over their fur, but the bracket would not stay on the wall more than about 5 minutes. After a few minutes of being attached to the wall, the bracket popped off of the wall, leaving the tape attached to the wall. I restuck it a few times always with the same results. Am now wondering how good "PetGuys" return policy is. I purchased three thinking they'd be great for friends with kitties. Oh well.
Consflexible plastic; the combs don't stay flat in the brackets as the plastic has warped a bit; "mounting" technology (tape) is ineffective
