Review (1/5): no go
I tried two pair of fresh batteries, from different packages.
No go.
Contrast this with my similar model from Oil of Olay. It didn't come with extra brushes or a plastic case and two boxes bound for the landfill. Yet, it has run for years. Despite dropping it in the shower a couple of times. And it was half the price of this $60 version.
If it starts off this bad, I would not want to risk what it would do a month or two down the road.
