Review (3/5): It worked fine but would get really hot and needed constant tightening ...
None of the attachments would work on the couple of blow dryers I tried. I finally got it to work by having it halfway open at the attachment end as it splits into 2 and had it only held on by the metal attachment. It worked fine but would get really hot and needed constant tightening and adjustment. Much easier to just use a comb while blow drying.
