It's called Tangle Fix and it's a little cheaper than the Tangke Teezer ($7.99).
I never jumped on the Tangle Teezer bandwagon since I like finger detangling, but my mom picked one up for her relaxed hair at Target. I'm afraid to try it lol.
I was afraid to use that type of brush at first. I read a bad review from a long hair natural and thought "better not risk it". However one came with an order I got form macadamia natural oil. I tried it on straight hair and loved it so I decided try it on my natural hair and loved it just the same. That brush works way better than denman brushes and wide tooth combs to me. Great detangling with hair loss equivalent to finger detangling on my hair. I don't know how to beat that!
