Review (4/5): Great Travel Diffuser
I read other reviews and agree and when the product is heated up, it can sometimes collapse if it is pressed against your head as others have mentioned. However, I purchased this item for travel. So thrilled to have found something that collapses to take up so much less space than a standard diffuser. It doesn't take that much effort/care to prevent it from collapsing during use. For my use, that is a small price to pay for the benefit.
