[This review was collected as part of a promotion.] I travel. And one charge lasts about 2 weeks. The shape is comfortable in my hand and the control button is easy to use. I like the brushing timer and that I can choose to use it or cancel it. And the unit, as a whole, does a great and comfortable job of cleaning my teeth. This is reflected when my hygienist doesn't need much time to do my semi-annual cleaning.

Different, and really like it so far.

Our dentist said these among the best. It takes some getting used to as it is a bit slimmer and longer than I am used to. Read the instructions and work on changing old habits first. I like the tone that tells me when to move to another of the four areas it suggests, and it shuts off when 2 minutes are up. You may want to order extra brush heads at the same time and try a couple of different ones out. Battery seems to last well too.
