Bests & Worsts Reviews from Amazon

The many good reviews for this Oral-b 1500 led me to take a chance on getting a "good one". Right out of the box, a quick few second test .... runs fine. Put it on charging base, indicator light flashing, all is good. Some six hours on the charger later, nothing, nada, kaput, total fail. It simply will not turn on .... period. I will give Amazon full credit for their very prompt and helpful service getting an immediate replacement on the way. Thank you Mary, you did good. I'm not so charitable with Oral, this failure is pretty well known and documented at this point, and it seems that by now it should have been resolved. Hoping that the odds now favor me for getting one that works. Two months of flawless performance since initial review. Had I received this replacement one first, it would have easily been four or five stars.
