When I received this toy I had really high hopes. It came in a plain brown cardboard box; inside was a Purple box with the toy clearly visible through a clear plastic sheet with the name Vibrating Nipple Clamps on it. The control box is soft and has groves that make it sit nicely in the hand. The cable leading from the control panel to the bullets is long enough that it won't pull on the nipple Clamps but not so long that you need to worry about getting wrapped up in it. The clamps themselves are pretty standard metal, with rubber nubs on the clamps themselves to protect them from the sharp edges of the clamp.
For those who are new to using nipple clamps, there is a screw or pin in the clamp that can make it tighter or looser depending on:
1)How large your nipple is and
2)Your pinch tolerance.
In the case of this toy the Pin serves a different purpose. Stabilizing the vibrations of the toy. More on that later. There are 10 modes on the bullets. Low, Medium, and High speeds followed by 7 different patterns. You either need to cycle all the way through the 10 to get back to the low setting or you can turn it off and back on to get back to setting number 1 as the bullets do not have memory like some higher end vibes. It takes 2 AAA batteries, so I would make sure you take them out before storing them because if this isn't one of your favorite toys and you aren't using it regularly or you aren't changing the batteries out, they can corrode and destroy the mechanism.
Now on to the fun part. I had never incorporated vibration into my nipple clamps, and I have normal nipple clamps, screw "clamps," and Clover clamps. Besides the clover clamps all of them can be adjusted to how much pressure I would like, much like these. As I have used clovers before, I knew that I wouldn't need the pin that made it looser, so I loosened it to the point that it wouldn't be an issue. I do have to say the pin is sturdy. It doesn't slip either way and I could easily use it without having to worry. When I turned on the toy, I wasn't expecting much out of the lowest setting. However, when I turned it up to medium, I still didn't feel much and just a little bit with the highest setting. I adjusted, I moved, I turned it up and down, pulled, twisted and still didn't feel much from the vibration. The vibe, being at the end of a clamp, seems to lose most of its oomph while it travels along the clamp. The one thing I didn't try during my first try was moving the pin at all.
Let's try it again!
When I pulled it out for the second time, I was pulling it out because I had lost my normal clamps, and I didn't want something as strong as the clovers. I thought, why not give it another go. I turned it on, and still no go, but while I was trying, I heard the annoying rattle of the pin and screwed it in so that I wouldn't have to hear it, and WHAT. A. DIFFERENCE!!! The vibrations weren't all over the place and were so weak. They were more focused and stable. I thought, 'Surely it isn't this simple.' and unscrewed the pin. Sensations were gone. I Screwed the pin back in; sensation again! Now, I'm not saying that it was the strongest feeling for me, but it was there. I tested it again and put the clamps closer to the end of my nipples, and it was stronger there. I would recommend doing this unless you are hyper-aware of the state of your nipples throughout the process of your sexual encounters, but I took the rubber nubs off of the ends, and it did increase the vibrations without the rubber. The rubber nubs must have been deadening the vibrations because that was also another substantial difference in the power behind the bullets.
I believe this toy could be improved by having the vibrations on the rubber nubs themselves, and I'm sure there are those toys out there. If you are new to nipple clamps and you want to explore, this is a cheaper way to go to be hands-free with a vibe in hand and on your clit at the same time of having the vibes on your nips; however, if you are more experienced, I would say to go for a toy that is better made and give that one a go. I know that's what I'm going to do.
