Product Rating: 1 Star - It's crap. I don't recommend it. | Power Rating: Mild - Enjoyable but not orgasm inducive. | Texture and material construction: The Duetto is made of silicone, which is a plus for cleaning. We boiled it the recommended amount of time to sterilize it, and it was just fine. The dildo had multiple small holes in the silicone -- which Vamp disclaimers as being normal in a hand-poured silicone product. Given that silicone is non-porous and can be boiled to sterilize, small holes are probably not much of an issue. | Review: My wife and I bought this dildo to use with the SpareParts harnesses, but found that the sharp angles of the piece really didn't work for us, either with or without the harness. We had difficulty attempting to get the Duetto sitting in such a way that both the giver and the receiver were comfortable with it. This might be less of an issue with the softer Duetto, but the Firm was a little too firm to be effective for us. Because this one is relatively expensive, I wouldn't recommend it unless you already know that you and your partner enjoy firm doubles (like the Feeldoe): it's a lot of cash to lay out for something that -- for us, at least -- turned out to be a failed experiment.
