The rubber is flexible and not oriented to producing sizes. This can be seen when pulling. During sex you realize minimal that what is about it, but once you get into the phase of enjoyment, you no longer feel it. It is robust and even after ejaculation, it stays tight. Peeling is extremely light. It also stinks not abnormal for chemistry.

Conclusion:
Buy recommendation, it is worth the money. However, anyone who runs several times a day should be guided differently, because the price is quite high then.
