My Philip's sonicare 4700 wont charge or turn on and only had it 9 months. I dont have the receipt. I won it at my dental office in a drawing which they will vouch for. They don't have the receipt . They said they buy in bulk. Told me to contact Philips cause its has a 2 yr warranty. I hope they replace it. Pretty crappy it pooped out only after 9 months of use. It was well taken care of and cleaned weekly!
