I consider this post more of a warning than a review. When I saw this, I thought it was a great idea and went and purchased it at CVS the same day for $12.99. I don't know that it cuts down drying time significantly (the microfiber "bristles" can only hold so much water) but, IT DAMAGED MY HAIR. After two uses, I have a lot of breakage at the top of my head that wasn't there before and it made it frizzy during blow drying anyway. I would stay as far away from this as you can (which shouldn't be tough...lol). It's going to take months to repair the damage this did.
