Well, since this is my first, and the first one i had the chance of buying i did some research but im not an expert. I did want one magnet in my thinger, but had no idea the round one or smaller would be better. So far it is 4 days of healing. The hyper sensibilitie is now gone. I can stary play with clips and im starting sense some eletric fields. I do feel it very steady and firm. So it does not feel like giving me any pain or moving toward the bone… but lets see how it goes with time. I could move a small coin, way havier then a paper clip with no pain, i think if you have a large hand with a hard and kind of fat thingers it seems like a good place. But maybe if your skin is thiner and soft , and more delicate, maybe it would not work… but dont know… just guessing…
All the best…
