Review (5/5): Sonicare e3000
This brush is awesome. I've had mine for well over a year now and it is still going strong. The other reviewers that speak of the water getting into the battery compartment; they are correct, it is a poorly designed watertight compartment and the rubber o-ring does tend to stop sealing correctly after you change the batteries out one or more times. However, I have come up with a very simple solution: when you first get the toothbrush, remove the end cap and lubricate the o-ring with plumbers grease. Granted, I'm sure alot of you do not have plumbers grease handy and if that is the case, petroleum jelly will work just as well. Make sure you apply liberally to the o-ring all the way around and once you place the cap back on, you can wipe any excess from the outside. Voila, now you have a watertight seal that actually seals.
