To try out this thing is great. But has not as much power as you would expect. The vibrating egg is waterproof (well, I think anyway - between cable and housing is a bit more air), the operating unit does not. Sharp edges, there are fortunately no. Is a pleasant feeling.
But: After several operations slowly releases the mirror coating at the interface of the egg. Therefore you should use this product for you to try, but not as a permanent toy.
Conclusion: For the price top! But a star deduction, because it is not lasting.
