Followup to Oral-B toothbrushes failing, what to get

[Spiff]

Interesting. I've had my oral B professional 9000 since, probably 2002. It is finally dying an agonizingly slow death. I have never discharged it to empty. I have always kept it on the charger ring. It now barely lasts 1 day without sitting on the ring. I'd say that's pretty good for 18 years. No! 19 years!

I'm looking at another OralB. I have found that the round head of the OralB does an awesome job of getting at my back molars and beyond. I got all my teeth, too. Nothing pulled.
