I got my Fort yesterday and wore it for a few hours after it arrived. I found it to be pretty comfortable and i like the weight of it, although naked it can take it's toll on the balls. I wear tight breifs anyway so it works out pretty good. my main problem with it was that all the cutouts, vents, pee hole, etc, seemed to be sharp. they were cut out but the edges of them were not beveled or rounded at all, making for a hard or sharp edge. (by the way, i bought this on ebay so i'm maybe a little worried i got a fake) has anyone else experenced this issue? Also, the seems down the sides on the inside werent terribly smooth and where they meet at the opening at the tip there was a sharp edge on each side. anyway, i used a grinding tool on my dremel to smooth everything out. all the problem areas are inside or on the bottom of the tube so it still looks just as nice everywhere else after the smoothing. I wear two rings (second largest and 3rd largest) behind the balls and use the small spacer between them and the cage. I can already tell that pullout would be much more difficult than the cb6000 i have had the past 6 months. the two rings also help to prevent it from hanging so low, although it does add extra weight. Like i said, i kind of like that. it seems slightly shorter than the cb6k and has a bit more room inside the cage, making it a bit easier to put it on. Also, the weight of the device makes it much more difficult to have an erection which pulls it away from the body because it's pulling down pretty hard on my cock. I would say it does make my balls hurt a little, like blue balls, compared to the cb6k but i'm sure it's a matter of getting used to it. I never owned a cb3k so i can't compare it to that but i like the feel and love the look. wish it came in a gun metal finish. OH, and i get NO pinching and pulling on my pubic hairs like the rings do on my 6k. that was highly annoying to me and i really hoped this device did not have that issue so i'm pretty happy. The wife has me unlocked right now so i'm testing it out and will show it to her next time she locks me up which should be pretty soon. hopefully she will like it and not be upset i purchased it without telling her.
