Review (3/5): Good idea, but collapses with heat.
I bought this for travel. As it turns out it has not fit on the majority of hair dryers provided at hotels in the US and abroad. When I’m able to use it on a dryer that it will fit on, it works well for about 1 minute. After 1 minute the rubber heats up and it will no longer hold its rigid form and collapses…making it impossible to dry your curls upside down.
With my most recent trip I gave this one more chance to work. It was nds up being very frustrating. I’ll throw this away and buy a better one.
