I give it two stars, rather than one, because at the end of the day, this does collapse to fit into my suitcase for all of my international trips, which means I do not have to bring both my dryer, diffuser, and adapter/converter for the plug. Now I can just use the dryer at the hotel.

Really like this product. Fits on the 3 different dryers I have tried thus far. Very light and easy to pack. Definitely recommend purchasing. Description is very clear as to the type of dryers the product fits on so read first before purchasing.

Love this. Took me a little while to learn to work with this diffuser but now I would not use anything else. Does a great job. Travel with it and use it at home. My preferred diffuser.

Doesn't fit on my regular hairdryers, only on my mini travel one. Very disappointed.
