I picked this up hoping it would make a difference in my blow drying time (I have long, wavy-ish hair) which can be upwards of 30 minutes in the winter. I was sort of impressed by it at first, but I think it was a placebo effect - I don't think it actually makes much of a difference. If it did reduce my drying time, I would say it was only by 10%, 15% tops. The brush itself is fine - it brushes through wet hair without snagging and what have you. But for $13, I expected some results from this and I got duped. If it sounds to good to be true, it probably is and that was the case for this brush.
