Query: Pinch and Die

I guess you really get what you pay for with this "powered" tooth brush. It stays powered for about 2 brushing sessions, and then for the next 10 you think this is the last time - it is going to die mid brush. When it dies mid brush and you have half of your mouth all nice and brushed and a mouth full of paste. Then you are forced to use something else to finish the job. I bought 2 replacement heads at the same time. The next day I had to buy a 20 count battery pack. Cheaper than buying a new "powered" brush. I just hope they last me through the 2 additional heads. All that said... that isn't the worst of it. It pinches my tongue and cheek, I thought I just needed to learn how to avoid that, but now 3 months into it, this morning I had 5 pinches.
