I purchased the Oral BIO series 3 last May. The toothbrush started making a loud buzzing sound after a couple of months. Called the P&G services enter and they had me ship it to them. Not sure if they repaired it or sent a new one, but the replacement made the same awful buzzing sound. So I went through the same process and had it either repaired or replaced again. Now two months later it’s happening again. I assume that they must be “repairing” it and sending the same one. Surely not all of the toothbrushes are defective. Called the service center again and now they expect me to pay for shipping it back to them. They say they don’t think it’s under warranty. I submitted through their link the invoice for the original purchase and they just keep sending me in circles to send it again. I will not buy another Oral B product.
