I am loving this nifty little beauty gadget! It really is wonderful to use, It is completely waterproof so you can use it in the bath or in the shower and do not have to worry about it getting wet. It is a sealed unit with a high tech charger. It does a wonderful job at removing dirt and leaves skin feeling like you have had a facial and a scrub. Easy to use and i love that the brush heads are replaceable so you can just get a new brush every 3 months. I have noticed a viable difference in my skin since I started using it.
