I have the 1875w Professional Tourmaline Hair Dryer and the diffuser that came with it is crap! It is so easy to knock it off the dryer while you are using it. This diffuser is not only stable but it’s much bigger so I diffuse my hair so much faster than the old one. Shoulder length blue damaged curls so you can compare.

Great defuser. It really helps me achieve some curl. I like the size of it. It is a bit big for my hairdrier (wobbly), but still usable. I do pack it with me when I go places, but it's big so not that convenient.

Great waves and curls. Love it!
