Query: Better than Oral B

I was an Oral B user for over a decade until I had trouble finding replacement heads. I purchased another Oral B - this time the Cross Action (budget-friendly) but the unit burned out in less than 6 months. I was so annoyed that I thought I'd give the Sonicare line a shot and I'm very glad I did. This toothbrush gives a MUCH better cleaning and just feels better on the teeth and gums. I highly recommend.
