My fiance got this so I could try c-rings out. It came in a basic package. It had some of the normal shipped plastic smell, but when I used a toy cleaning product the smell went away. It looks like its made of thermoplastic rubber just like many auto part bushings so it should last for awhile. TPE is highly "impact" resistant, so it should not be a problem banging away with it. TPE also allows you to use silicone or water based lube.

I tried it first by myself to see if they did work like they are supposed to, and it did make things somewhat harder for longer, but it wasn't an impressive gain. I used some KY to aid in the trial because I was afraid to take care of business with no lube. I felt like stretching plastic and bare skin would be a bad day. It was sort of a new experience but it wasn't a game changer for me. We tried it as a couple a few weeks later and it wasn't mind blowing for her, but she said it was fun because it felt a little different. She did like the feeling of the little nubs when they touched her lips and clit though. She said it was like a tickle, but a good tickle that wasn't too intense. We tried it again a couple weeks later after a few drinks and it was pretty fun because, as many guys know, things sometimes don't work as well after drinking. It helped keep me focused that time.

I have never had any problems taking it off because I just let things relax before removal. Its a basic c-ring for beginners, and as long as you take that and use that as your mental guideline, you wont be disappointed.
