Bargain Sonicare
I have been using Sonicare toothbrushes for 15 years or so. Every time one fails, I seem to get less operating time before failure out of the replacement toothbrush. I then discovered this battery operated model. They last 2 to 3 years. This is still too short, but at least I'm only paying $20 to $25 for each unit. And this model works as well as it's more expensive siblings (although without the bells and whistles of the more expensive models).
