I bought this for my daughter. She has incredibly knotty and super long hair. At 6yrs old, it's NO fun brushing out her hair when she's crying due to the pulling and brushing. I hoped this brush would bring some relief, but definitely did not and after one or two uses we didn't use it again.

Perhaps for thinner and shorter hair it would be more effective. I decided to try it as it was much cheaper than the tangle teezer, but in the end got the tangle teezer anyways.
