Highly recommended!
I highly recommend this diffuser for travel. I bought this for a trip overseas and was pleasantly surprised at how well it worked and how well it fit  hotel hair dryers. We stayed in three different hotels and I was able to get this diffuser to fit on the hair dryers at all three of them with no problems. The silicone makes it easy to fit on pretty much any standard size hair dryers, and I didn't have any problems with it collapsing during use. Highly recommended for travel.
