Review (5/5): Just as good as the rechargeble
I bought this Sonicare brush on a "trial" basis and I've found that it works just as well as the more expensive ones with the rechargeable batteries.
There are two great benefits:
1) Low price of the brush.
2) Space saving in that you don't have to have a counter space/electrical plug for the charger.
I've had my brush for over 3 months now and still using the original set of batteries provided. No issues whatsoever.
I also don't understand the reports of water leaking into the battery chamber. I think maybe those are with the earlier designs but clearly, the one that I have is completely sealed and you should not get water in there unless you completely submerge your unit.
