This toy is used for tightening vaginal muscles. It was my first time using a vaginal exerciser. I was a little surprised at how large both balls were when they first arrived. They slipped in pretty easily with a little lube. This product is best used inside the house when first getting used to having them in. They do slip out if you forget to keep your muscles tightened, so i recommend using them a few times before going out with them in. Once you're ready to remove them, just tug on the string and they easily come out.

I do wish I had purchased smaller ones to begin with because I feel as if these are just a little too big and will slip out too easily.

The material had no odor, and was easy to clean. This product can be cleaned using soap and water. They have smaller balls on the inside that provide a very subtle sensations while they are in, but nothing that will send you over the edge.

I did not like the string on the balls. The string that connects the two is rigid and not very flexible. The long string that is used to remove the balls is also rigid, and since it does not flex, it sticks out and is a little uncomfortable when wearing pants. This product would have been better if the string were not made of hard rubber, but a more flexible string instead.

This toy does exercise your vaginal muscles. I've used it several times, and it reminds me to keep my kegels clenched. I feel that the balls are a little large and slip out very easily. In order to keep them in, you have to be really really clenched.

I wish they came in a case to put them in, as some other vaginal exercisers do. It arrived in a plastic box, which I reuse. It is a pretty easy toy to clean, and since it is plastic it also dries easily. This material is compatible with pretty much any lube, I used a regular KY and had no trouble at all. This product is easy to store, it is pretty small so you can hide it anywhere if you need to.
