Pulling out tools to put it on my hair dryer is ANNOYING!!!
So the concept of this attachment is a great idea, for those that have a good hair dryer that didn't come with an attachment.  However, I don't like the fact that I have to pull out a screw driver to adjust it.  I shouldn't feel like I'm working on a shop project to attach it to my hair dryer.  I wish there was some other way to make the comb adjustable, it was pretty frustrating but I finally got it attached to the dryer but it took longer than I had anticipated.  Once I did get it attached it was fine but metal adjustable band makes me only give this three stars.
