The diffusers it’s self is light weight but once it is on the dryer it adds weight to the dryer, if that makes sense. I do find it a little hard to put it on to the end of the dryer and I find that it will collapse/fold while I am using it. I probably will look into other options.

It works just as described. I used to always have to pack my full size diffuser when going away. Now I just need to pack this compact attachment.

Had to get a different blow dryer to fit this nozzle. I have long hair, so on a cool setting, just know it take very long to blow dry with the Diffuser. Works as expected.

Product as Expected

This does not fit my dryer but my boyfriend was able to shove it on.
