Unbreakable... sure. Thermal... not so much.
I was excited at first because I had an attachment for my babyliss blow dryer that the company did even make. However, I had to keep retightening every use to avoid popping off, and my blow dryer got so hot it eventually warped the inner cylinders. Now it can’t even hold to my dryer. It did the job... while it lasted.
