This extension has not worked for me. It might work for some, but for my significant other, it was excruciatingly painful. She could not take the extra width and nubs, and we couldn't even get my penis all the way inside her, so I have no idea how the length would have worked.

The TPE is fairly flexible, which actually makes it a challenge to put on the penis. It wants to both retain shape, but also to stretch, it's very interesting. It feels like an incredibly thick condom for the man, and like a spiky death cactus for the woman.

When I first got it, I was very curious about how the shape and nubs would stimulate. After one trial, I realized that this was destined to hurt her, but we kept trying just to give a full accurate review. According to the packaging, it is reversible, but that didn't work for intercourse. It DID make it easier to clean. While challenging to put on, it was comfortable for the man. It might start off as too long for some men, and the packaging describes it as trimable.
