I bought two of these and was really excited to open the box and experience their power. at one point, I was attempting to bring them together anti-pole at which point they decided to spontaneously flip and dislocate my pinky. The experience was quite painful which caused me to release my grip. They dropped one my shirt at somehow managed to only be seperated by my shirt and my nipple underneath. Now, in certain situations, I actually enjoy my nipples being pinched however this was not one of those instances. So imagine, a 50 year old, slightly obesse man hopping around the room yelling with what appear to be a gigantic nipple ring attached outside of his clothing..... This paints a pretty accurate scenario of the power of these magnets. BTW.... I was able to remove the magnets from my nipple and shirt, however, I am unable to remove them from each other!
