Review (3/5): It works great - after you hack it
I just got a new hair dryer (VAV - Vivid and Vogue 1875w hair dryer) and I was excited to get this nozzle. I fit it around my blow dryer, ran it through my hair once and POP! It fell off the dryer. Thinking I didn't assemble it correctly I took it apart, put it back on the dryer, ran it through my hair and POP! It fell off again! It was falling off because there was nothing on the inside for it to grip. When it's on the dryer it's just smooth plastic against smooth plastic. So I cut a rubberband, wrapped it around the nozzle of my hair dryer, reattached the straightener on top of the rubberband and tried one last time - it didn't pop off!
I can attest that it truly is unbreakable as it hit my hardwood floor 8 times and didn't break. Now that I got it to stay on my blow dryer it does a great job of straightening my hair but I can only give it 3 stars because I had to hack it to get it to work.
Note to the Willie Morrow: put a rubber ring around the inside of the nozzle!
