Does this sound like a good brush?

[Mirg]

My best friend bought a brush a couple of months ago and i used it on A.j. It was 2-sided, one side was kind of rubbery bristles, like on a rubber mit, and the other side was straight, plastic bristles that retract into the brush so that the fur comes out from between them. It seemed like a good brush, but does it sound good to everyone else? I really liked the rubber side, it got the loose hair out so good. I just want to make sure it sounds good before i go and buy one (its about $10 each). I was going to post a picture of it, but i cant find any. I have been using a wire-bristled slicker (i think) brush, but i dont like it because it loosens some of the hair, but doesnt pick it up at all.
