Everything that has already been written is true:--battery runs out of juice too quickly--noticeable decrement in performance very soon after "full charging"--has to be refilled many times during a single use--have to be wary of angle or mechanism doesn't function properly/will spill(chamber doesn't stay closed)--isn't waterproof(ironic, seeing how it will be used in the bathroom, if not the shower)The only reason I gave it 2 stars is because it is really cheap(the cheapest I could find), but I will be spending my money on something better for my next one.
