    Messy, only worked 7 months, bad CS

    I had earlier oral-b elecric brushes and they lasted 10 years with minor loss in battery fade. Was excitef to upgrade to this series 9, at $300. Was thrilled, but quicky learned that needed to brush directly over sink or it would spray and drip toothpaste eveywhere. I was adjusting. Then 5 months in, it would die after 20 seconds (battery said 96% when started). I thought it was a fluke. Then it happened every time. I called oral b, they said if i mail it in, they can try to service it. I’d be without a toothbrush for 6 weeks. They dont just send out a replacement. They dont trust you that the product is defective. They dont trust youll send it back. They offered send me a manual $5 toothbrush to use temporarily. The toothbrush is a lemon. Many others have same issue with this model. Oral-b doesnt offer to replace. I would avoid this model. Im still looking for a replacement but scared to buy another high end oral-b product.

    it's a really bad design that the brush head comes with a hole or even two. water and toothpaste trapped in the head becomes black filthy suff over time. Seriously why Oral-B does this? for better sale of heads? pushing customers to Philip?
