Review (1/5): Cheap but...
I had purchased this initially and while i was impressed in the initial few months, that impression didnt last for long. I unfortunately told my wife about it and had her buy it too and now we have 2 unhappy users.
Mainly its the battery compartment.. which is in the bottom (blue cap). If you dont dry up the brush before storing.. then overtime the water can enter the batt compartment and corrode the batteries. The corrosion prevents the batt caps from even closing... which prevents the mechanism to operate. Both the brushes are not working as of this morning. I can see why its cheap(er).
We are planning to go with the real (waterproof) sonicare.
