This brush is a LEMON!
I have to chime in with the other reviewers.  At first I loved this brush.  It feels amazing in your mouth (hold your jokes please)!  But within a few weeks or months it will stop working.  I actually bought this brush at a drugstore on sale for $20.  The first time it died,  they exchanged it for me.  When the 2nd one died, I was able to get a full refund.  This brush is a lemon.  You should know and you've been warned.
