I got these some time ago and just haven't got around to writing a review. They are interesting pieces of plastic.

They will suck your nipples into the cylinder (or any other body part or skin) and provide a decent amount of suction. It's enough to hold fast and create small purple circles (if you leave them on long enough), though I've never found the circles to remain very long. The main problem I have with them is that the suction is not enough to keep them on through play. I found if you bump them, they fall off. One of my favorite places to use them is on my clit; they provide just the right amount of suction there for me. They will engorge my clit and put me on the edge of orgasm. Using them on my nipples is fun, but I found that I don't get as much stimulation as I would like. In my opinion, I find cloth-pins to provide more of the sensation I want.

Also, this toy had somewhat of an odor when I got it. It was not enough to turn me away, but there was a faint odor nonetheless. With time the odor has faded, and now they are like any other toy in the box.

These are very easy to clean. Warm water and soap will work well, or if you wish you can use toy cleaner on them. They are made of rubber, and rubber is porous, so they are not as clean as they may look. I would not suggest sharing these with anyone else because of they are porous. It’s not possible to cover them with a condom and have them still work. Either water or silicone based lube can be used with this toy, though I don't think you will need any.

They can be fun but there are similar toys out there that are made with better materials.

I just tend to get frustrated with these. They fall off all the time. I think they need more suction.
