The extra 18 cm really does make a difference once it's on, and the added girth was more noticeable than I expected. It stays put without slipping, which was my main worry before trying it.

The realistic texture genuinely surprised me, it doesn't feel like cheap rubber at all. The extra 18 cm of length and added diameter made a real difference, and it stayed comfortable the whole time.

Wasn't sure the 18 cm would feel right but the diameter increase is definitely noticeable. The material has enough give that it stays comfortable, and cleanup afterward took me like two minutes.
