Review on Advanced Battery-Powered Oral Care Electric Toothbrush by Fred Reid

Ideal for on the go. My device has a tricky switch, but there is a small problem. Advantages Easy to find brush head Fast and ergonomic design. Does a good job of cleaning up expired battery life. I've been using it with the original batteries for a couple of weeks so I know how long they will last. Good that batteries are included. Ready for immediate use. Tip Use disposable lithium batteries. It runs at full speed on alkaline batteries and gradually slows down when the batteries run out. With lithium, it runs at full speed until the batteries run out. Keep a spare set as it may die off during cleaning. Lithium batteries are lighter, so less weight improves ergonomics.
