As a tea drinker, I contend with the stains that tea leaves. After my dentist recommended against using the whitening toothpastes, due to their abrasiveness to gums, I thought I was going to be stuck with healthier gums but stained teeth. Sonicare without whitening toothpaste makes my teeth look better than they did when I was using a regular toothbrush with whitening toothpaste. (I feel like a ditsy, smiling spokesmodel here but I really was impressed.)

My only complaint has been getting used to brushing with an electric toothbrush--a problem I suspect I would have with ANY electric toothbrush. You have to get in the habit of putting the Sonicare in your mouth, and closing your lips around the brush BEFORE you turn it on. Otherwise, you wind up with toothpaste decorating your bathroom mirror, your clothes, and pretty much the entire area around your bathroom sink. This isn't something easy to remember when your half awake and brushing your teeth. My other only complaint (OK, I guess I have two) is that Sonicare turns off after about two minutes, the time it has determined it should take you to brush your teeth. Being a little slower with things, I would rather turn it off when I'M done, not when it thinks I should be done. Apparently this design feature is to avoid over brushing. Since you can turn the Sonicare right back on again, this isn't a problem.

I can't speak for how long the charge lasts as I have left it on the charging stand when not in use. Apparently, however, the Sonicare is designed to hold a charge for quite a few hours, to allow you to take it with you while traveling, for instance, without having to bring the entire charging stand along.
