Review (1/5): DON'T BUY THIS!!!!
Dont buy this.
Other Sonicare products are good but this battery operated is not worth your money.
Reasons:
This will stop operating when the water enters to the battery compartment. No matter how you do, the water enters the battery compartment and causing short circuit.
Second, the plastic bottom that closes the battery compartment will break and no longer can be secured.
Just dont buy this.
I dont understand how they could come up with this design.
If the bottom of the battery closure is of spin closure type, then it would be much better.
