While the rechargeable brushes from Oral B and Phillips offer higher brush strokes, they are planned obsolescences with the highly difficult to remove cells. It doesn't matter if you buy a $300 toothbrush or a $50 toothbrush from either of these manufacturers, each rechargeable product faces the same problem.
Since a lot of OzBargainers own Eneloops, the reasonable option is to buy a battery-powered toothbrush. But which one do we choose?
I've recently found this product that has rave reviews from Amazon.: http://www.amazon.com/Electric-Toothbrush-Battery-operated-r… . Has anyone used it?
Choice did a recent review on these….have a browse through the last year. I suspect your amazon one won't be in there. IIRC, the Oral B ones do the best with no major improvement in cleaning for better models. So stock up when cheap.
