Pretty nice
First time using anything but my fingers and it's pretty cool. It feels great, and does a better job of massaging the lather into my scalp than my fingers. It's particularly nice because I get psoriasis/seborrheic dermatitis on my scalp and this device does a good job of getting the shampoo deep into the scalp. It also looks like it would be great for applying dry shampoo, but I can't speak directly to that yet.
