This was my first diffuser, so I hard time figuring out how to make it work for me. This is no fault of the product, but of my frizzy cavegirl locks. I don't really have anything else to compare it to, but it fits on both of my blowdryers, and works great when I use a product for wavy hair, like Paul Mitchell's or Davines. Definitely worth the money, if you're an idiot like me and tossed the diffuser that came with the last blow dryer purchased. Worst mistake ever! But, on a happy note, this does the trick!
