BAOVERI Sonic Electric Toothbrush for Adults

From the beginning, I really liked this rechargeable toothbrush - all except the maddening placement of the controls, which lie just about directly under the thumb - and therefore, make it difficult to hold without switching off or changing the modes. But there's a more basic problem: after about 16 months, bye-bye. It won't hold a charge - I began getting less and less time out of each charge from the time it was about 12 months old, and now - a few months later: dead. MIGHT turn on but then turns off after 5 - 10 seconds. And that's only when it has a full charge and only WHEN the power on knob works. Which - I suspect - has become pretty random. I'm relieved to see that as of this writing, it's "Currently unavailable. We don't know when or if this item will be back in stock." Which is how its status SHOULD remain to keep schlock like this off the market. And I'm so glad I purchased a mountain of replaceable brush heads for it - which now, unless some lucky fluke arises, won't fit any OTHER new toothbrush I purchase.
