I have purchased a lot of items from Tenga and have a good number of items to compare this to. On the plus side, it is super soft! Easily the softest material Tenga makes. Very easy to clean! Amen to that. (The Spinner is the worst to clean. I've used it 3 times and I'm afraid to continue using it because it's so difficult to clean.)
The downside, as mentioned by another reviewer, the internal design simply isn't there. I can't even feel it with my fingers. The material is so soft, the ridges and bumps simply don't perform as intended. It's just a smooth sleeve. That's fine if that's what you are looking for. I wanted to try the Rocky Black, but it was sold out at the time, so I went with Silky White. I really want the stronger sensations, but I don't want to plop down another $35 if the results are the same. The product descriptions are near identical, so it's going to be a gamble on my part.
The sensation is pleasing, but it's completely smooth. There's no way to feel the internal design at all.
What I'd love to see is a sleeve that is open on both ends so the ejaculate doesn't get trapped inside. During orgasm, the sleeve fills up and all sensation is lost at the most critical time.
