Feels good
Feels good on the scalp.  I am confused as to why there is a power button on one side and on top it says open, as if batteries could be installed, when this is a manual massage brush.  Easy to grip with soapy or slick hands.  "Bristles" are gentle on the scalp but definitely get my blood flowing.  My hair is short and I don't worry a whole lot about tangles.  My daughter's hair is long and thick and I keep her hair pulled somewhat tight as I use this otherwise it will leave a ton of tangles in its wake.
