Review (1/5): Does not work - diffuser keeps slipping out of adapter
I purchased this adapter to use with an Xtava Black Orchid Hair Diffuser - for Blow Dryers with 1.8 inch Diameter Nozzle. It was displayed on the same Amazon page as the diffuser, and the diffuser came with instructions for how to use this adapter. So, I assume that they were made to work with each other.
This adapter is just a short cylinder of flexible rubber. It does allow me to connect the diffuser to the hairdryer. But, when using the hairdryer/diffuser, the diffuser keeps falling off.
Therefore, this adapter is not functional at all. Beware!
