Looking into purchasing a kink3d. I have only used metal devices for the most part. I did purchase a knock of cobra from Amazon and it was pretty flimsy it separated at the sleeve and ring allowing balls to slip through and also agonizing pinching at pins located at locking device had to tie strap it to keep it closed so that it would not allow ball slip and pinching. Has anyone had this issue with the kink3d device? They seemed to be talked up well. Are they worth all the hype. They are pretty expensive. I am getting into long term chastity and was wondering if this may be the way to go? I am into construction and move around a lot of stooping and bending. Any info would be helpful. Thanks in advance!
