It's terrible, you waste your time trying to fit them in place and in the end, they don't offer anything special. I don't recommend them. If I were more malicious with the sexual aids, I would say I would use them in the water pipes. The plumber thought of making them.

It does the job it promises. The various sizes help with the variety. The material is durable and worth its price.

Very good product. Three sizes to wear as in the design. Personally, I use the 2 (for the base and the balls) since the other one is quite tight, not that it can't be worn but it's not for frequent use. But even with just the two, it offers a good feeling.
