I bought 2 of these brushes; one for a gift. I like it a lot, and my scalp feels good after brushing. Verily I feel that it's good, and following the job boards, I brush for at least 2 minutes for a good massage effect; I like it so much I brush my lot of time in the day! :) It was a little hard at first, but my skin is quickly sy accustomed. I think by that account the large brush should be softer & flexible with greater flexibility (I have one, but kept aside to make a gift). By cons, a tiny hiccup - I of static eletricity with the brush but very little, and I ressoud little problem by painting me with bamboo comb Immediately after each brushing & everything is in order ! :)
