Review (1/5): Hard to Install, Hard to Use, Breaks easily.
It seemed like a really good idea, except the material the item is made of is not very good quality. Second the sizing in the description is far from accurate. I have a dryer that is well within the specs and it barely fit on the end. I barely got it to fit while using a few tools and having a friend help me.
As far as actually using it - I have curly hair, so I tip my head upside down while using a diffuser. This unit just collapsed over and over while I was drying my hair and crunching my curls, making it really hard and time consuming to use. On the sixth day of using it I accidentally dropped my hair dryer with the diffuser attached. The base of the diffuser tore right in two, making it totally useless. The fall was maybe a foot to the ground. Definitely would suggest a hard pass on this item, just buy something else entirely.
