I used these while doing chores and grocery shopping. Let me tell you, you will know they are there the whole time. I used a little bit of water based lube to get them in and you just set it and forget it. You will immediately start feeling your muscles clenching to keep this in. I would not use this anally, because that's not really what it's meant for; there isn't much of a flare at the bottom to keep this from getting lost.

It is made out of pure silicone, it is a 10 on the safety scale. Very safe to use internally. Very soft and comfortable material. There is a small, slightly raised design on the side of the balls that can be felt with your finger, but not when it's inserted. The pull strings are very stretchy and strong. The balls are hard and they have no give to them.

I'm not so sure I like the design of these, because there is way too much cord between the balls. There is 2 1/4 inches between the balls and the balls are 1 3/8" diameter. Now I thought that would be a good size for me, but the balls are a little too big and when I insert both balls, they end up touching when inside of me. So the connecting cord was bunched up while inside of me and it was a little uncomfortable. It also pinched me inside, every now and then. I'm not sure if I'm so tight, because I just got over my period, and my body will loosen up or maybe I just need a smaller set. If you are on the smaller side, you can try them and see if they fit you, but I think I'm just going to try a different, smaller set. I didn't even really like the retrieval cord because it is uncomfortable when it's sticking out. The one reason I chose this over any others was because it was a seamless design, completely covered in silicone. No rough edges.

Granted, it was a little to big for me; I could still feel it working. It weighs 80g, which is 2.82oz. It has pretty good weight to it. Every time I stood up, my muscles would automatically start to clench to keep it in. You cannot hear the little balls jingling around while its inside of you. No worries there. I wore it for about an hour and when it started making me uncomfortable, I took it out. I would probably try this again later to see if it fits me better.

After use, you can clean this with a little soap and warm water. Make sure you store it somewhere where it's not going to get any lint on it, because it does collect lint easily. I store it in the original packaging, which is a simple cardboard box, with a picture of the exerciser on it. There are no instructions in the box. Which I was a little bummed out about. I usually don't use the instructions with any toy, but because this is my first exerciser, I wasn't really sure how to use it. Granted it's not that hard, but I wasn't sure how far this was suppose to be inserted or how long to wear it. I would also only use water-based lube with this product, because it is silicone; you wouldn't want any reactions that will ruin the material.
