Ok so is 9 months the normal longevity of these sonic toothbrushes? I'm really frustrated now, I've had oral B electric toothbrushes that last years. Should I just switch to Sonicare?
Here is why I think it's dead, I just charged it a couple days ago and when I went to use it it was completely dead. And when I put it on the charger, no lights came on like they normally do. I know the plug works fine because I have my clarisonic charger plugged into the same socket and it lights up when I put it on the charger. So it's getting power.
I don't leave it on the charger all the time, I only put it on there when it needs charging and then remove it when it's done.
Can I just change the rechargable battery in it?
