The unit is waterproof, it is used in the shower for the first few uses it is less painful when one is not accustomed.
The design is really nice and pleasant.
In the end, I find it very efficient even if he is a little expensive! But for a gift to a young girl who is reluctant to use an electric hair remover, this is a good quality / price ratio.
I advise my daughter when she has the age of shaving legs or underarms ... she did that 12 years ;-)
