Title: Good but you must use Li-Ion (high-tech) AA batteries
Review: A lot of reviewers have a problem with this brush stopping after a few minutes or high pressure use. I have been using this brush for a long time, but it is important to buy the Lithium-Ion AA batteries (for use in high-tech devices), because this thing drains power like there is no tomorrow. If you use the Li-Ion batteries, this brush will work fine and last for a long time. You can get these batteries at any store in the regular battery section.
