Died after six months
I got one of these, and it worked fantastically for some time.  I figured it would be a budget way to get the Sonicare clean while at the same time working through my enormous collection of AA batteries.  Well, it was good while it lasted.  Even at six months until expiration, it's still probably the cheapest way to get the clean I want, so I ordered another one.
