Review (2/5): Not “universal” enough?
I work in a huge health club where the locker room has a ton of different hair dryers available to use. I bought this hoping I could use it on any of the different model dryers. This diffuser would not fit over a single nozzle of the dryers. Out of desperation, I ended up cutting the part where the nozzle would go it (since it’s rubber it also tore a little) and I got it to fit. By destroying it. It works okay now but my suggestion is finding a stretchier rubber material that would actually fit over standard sized hair dryers.
