Review (5/5): Great and fits all size dryers from diff hotels.
Great for traveling. I don’t like the silicone diffusers because they get hot and start to collapse while drying your hair and I needed one for travel. This one is perfect. I’ve noticed the last time I put it on full heat power and the plastic notch inside is starting to melt. I won’t be using it on high heat anymore. Also try not to push the dryer nozzle to where it touches the plastic. Try to keep some distance to prevent this and from the dryer overheating itself.
