I got one of these brushes from a local pet supply place and some Petromalt to help Terra with her hair ball issues.

She LOVES the Petromalt. After only 2 days, she comes running when she hears me open the drawer that I keep it in. She's so thorough about getting it all off my finger, that she's nearly taken the top layer of skin off too.

The blade itself is great. In just one swipe, I can get a whole lotta hair off her and she seems to enjoy it. My only complaint (which isn't really even a complaint) is that the loop is so big (or Terra so small) that only parts of it are actually on her, pullling off dead fur, when I use it. I probably should have just bought a smaller blade. Live and learn.
