Doesn’t hold a charge
I loved this brush while it lasted.  Like so many others have said, it no longer holds a charge.  The first charge lasted weeks and I used it 3-4 times a week.  When it died, I recharged overnight, used the next day. Two days later, the battery was dead.  Charged it again, this time the charge didn’t work at all.  The light indicated it was fully charged, but when I went to use it later that day it was dead, again.  Lasted only a month.  Cheap, foreign product that I don’t recommend wasting your money on.
