Review (4/5): Excellent toothbrush
I owned a rechargeable model for several years. The battery finally stopped holding a charge. Instead of purchasing another rechargeable model, I bought this one that takes two double A batteries. It's very easy for me to transport in my dopp kit by removing the brush head, has the same power as the previous model and does an excellent job of cleaning my teeth. I highly recommend it. the only downside is this model doesn't sound an alert every thirty seconds to direct you to a different quadrant of your mouth. It is timed to run for 2 minutes and then cutoff. I can deal with that.
