Suits My Purpose
I'm pleased to have this scalp massager.  It works well, feels strong, but comfortable.  I feel it is stimulating hair growth but I do not have any evidence to support this claim.  It just feels good.  I use it twice a day and I find it relaxing.  Note:  I have not used it in the shower during shampooing, and honestly, I probably never will as I don't want to chance interfere  with the proper functioning of the battery operation.<br />I can recommend this to others.  Just make sure you have your own batteries on hand.  It's very easy to install the batteries!
