Never worked once.
Bought it as an add on to the itoothbrush. Charged it for 26hrs and the product would only activate when plugged in. The battery indicator never blinked as in the manual. I'm returning and getting a refund. It is also bigger and bulkier than expected. I have one for my traditional toothbrush that is battery operated and has worked perfectly. Too bad I cannot use it to travel with the itoothbrush.
