Sonicare Elite 7300 Toothbrush with Sonic Technology Review

I enjoyed this toothbrush while it lasted but the time it lasted did not make it a practical purpose.  The design, features and positive dental health attributes led me to buy this toothbrush and when I first got it, I absolutely loved it.  My dentist even commented at a check-up on how much better my gums were (this was after after 3 months).  Around the six month mark of ownership, the toothbrush started to turn off after a few seconds (it is supposed to go for 2 straight minutes and give a warning after every 30 seconds to let you know to change quadrants in you mouth - really cool feature).  I would repress the on button and it would work fine.  A few weeks later, the warning stopped working.  A few weeks after that, I was unable to use twice a day because it just plain would not work for two full minutes due to low battery.  Fianlly, it started acting funny unless I held my head really high or very low which I attribute to the base needing to be held in a certain direction.  All in all, gave up on it and tossed it.
