I was really excited to get these in to try them out. I've always loved having my nipples played with, but I've been too intimidated to get much of anything in fears that it'd be too intense and painful. They arrived packaged in a sealed plastic bag. The downside of this is that the "bells" of the nipple suckers were misshapen from the packaging. The silicone is very soft and silky to the touch. I did test these on different areas of my body (arm, leg, stomach, and even my face lol) to see how strong the suction is, and to try to find a technique that would ensure a good grasp and seal on my nipples. Unfortunately, since they were just a little misshapen, it was difficult to get a good seal anywhere on my body, and it took some finessing to get them to work properly. I did eventually practice attaching them to my nipples, but again I had trouble.

When it came down to using them during foreplay and sex, it was definitely a challenge. Once my S/O and I got them on, it's like the slightest movement would make them pop off. It was too much of an inconvenience to stop and put them back on, and with increasing frustration, we eventually opted of out using them this go-round.

When we did get a good seal, it was great. For me personally, it was just the right amount of suction to where you can definitely feel it, but it's not too much. I'm hoping that we can figure out how to reshape the bells to make them easier to use.

Keep in mind that these may be weak if you're experienced with nipple stimulation. It's also difficult to keep them on, especially if your partner is messing with your breasts or there's a lot of movement happening. I found they worked best for me when I was on my back, but I also have F-cup sized breasts. If you're a smaller size I'm sure these would work great for you in any position.
