This is my first purchase from the site, and I wasn't sure if the 65 would be too big for me. Ultimately, I find it very easy to use and insert. The material is incredible, truly unlike anything else you can find on the market. I highly recommend this brand, and this particular model is incredibly comfortable to wear. I'm French, and to anyone hesitating to order: shipping was very fast, and I received the plug in no time. I now understand why this brand is a benchmark. Happy stretching, everyone!
