The material gives it a really nice feeling, and the weight makes a noticeable difference. Overall I give it 4/5 just because of some minor flaws: 1) the smell of the material itself is quite strong, and 2) for some reason it is quite harder to clean than other products (dirt particles remain even after hot water).
For those looking to try this product, I say go for it! Just keep in mind that the material itself can be very harsh on your skin, so use it with the mini onahole provided, or if you want to use it directly, then use it with a lot of lotion, otherwise you can hurt yourself.
The price rating (3/5) is based on the price it had when I bought it, but now is cheaper.
