Compatible to the Dyson Airwrap. Works great, lightweight, and doesn’t make hair frizzy.

I love this diffuser. My hair does better with the cup style and I like this one way better than the Conair one I have always used. It fits perfectly on the UNIKARA, Professional Salon 1875 Watt Blow Dryer, Ceramic Tourmaline Ionic Hairdryer because it has a thin nozzle. The diffuser did come with a little thing to help it go on a smaller nozzle hair dryer too if needed. The cup is deeper than any I’ve seen on a diffuser and I love that. It’s a good size so it’s not going to be a space saver for travel, but if you don’t travel often, it won’t be a big deal for occasional travel like I do.

Wish there were no spikes on face....Flat would be great...

So it stays on for the most part but, fell off multiple times while in use.

I used to get worried lugging around a hair dryer when traveling but not anymore. This is by no means small, but it’s smaller in volume than a hair dryer + diffuser. It works, stays on tight and works great.
