Review (4/5): This goes with me on every trip now
This is oddly the best diffuser I've used. My hair comes out really great every time. It does collapse really easily while using it, so I took off one star for that. I travel for work a lot and it is so great to be able to use hotel hair dryers now and I love that it doesn't take up too much space. I haven't encountered a hotel hair dryer that it won't fit.
