Failure to charge after 2 months of use spoils an otherwise good product
Until this stopped recharging, It was a 4-star item; knowing this might be a problem I deferred review.  At this point, it won't charge and is dead.  So, let me review both pre- and post-death.<br />If you like ultrasonic toothbrushes, this is great.  Motor is strong, brushhead movement is less than a rotary, but on par with other top-end ultrasonic toothbrushes.  The ultrasonic motion really foams up during use, which is different than a rotary.  Body is solid, good heft and feel in the hand.  I really like the brushheads - connection to the body is solid, with no 'wobble'.  Overall, if you prefer ultrasonic to rotary, this is a solid 4-stars.<br />Until... it comes to recharge.  Arrived fully charged and didn't begin to slow for 3 weeks - which is a great charge life.  I plugged it in and recharged overnight.  This charge lasted two weeks.  Another overnight, lasted about a week.  After that, needed overnight just to turn on.  At this point, even plugged in, it won't power on.  Recharge is essential feature, with this failing in 2 months, I can't give it more than 2-stars.<br />I'm not the only buyer who reported this same behavior, so it isn't a one-off problem.  Fix the battery issue and it would be a solid 4-stars.
