There I was excited to try this on and wear it for my lady. It didn't go so well. Even without any instructions, it is very easy to figure out. Before trying anything on, as suggested in similar products, I made sure that there was no seams raised to cause cuts or rubbing. There were some but they are easy to smooth out. Inside the cage looked like they had already done it and didn't have any raised edges. Time to try it on, select the right size for the backing ring, they run a little small as I'm not a big guy in that department. Put it on and lube up the little fella, (also a handy tip for first timers), slide it in and all feels well... Almost. The seam inside of the member cage was nice and smooth but the area in which the pieces are molded and assembled was loose. Oh man, it grabbed the foreskin and wouldn't let go for anything. Luckily it didn't cut anything but it sure felt like it. We didn't even put it on fast or anything that would cause a separation in the seam. I took it off with some help from the misses and as soon as we undid the lock, the cage came apart in two pieces. It appears like I could glue them back in place but at this point, I'm going to ask for a replacement or refund as I have a very sore little fella and a broken unit. I guess it is true that you get what you pay for and I guess I paid for a pain in the foreskin...To be clear, I do not have a huge member so it definitely was not a too small fitment issue. It was a shody seam job on the cage.
