    Dear Lady Fox,
    “The Full Metal Jacket device I purchased is excellent!
    Well designed. Ergonomically well thought out, light but durable, easy to put on and very hard to get off if properly sized. I actually can’t take mine off without either destroying it or ripping my balls off (not into being a castrate).
    I am looking forward to getting the device in stainless now. It’s great that I was able to try it in plastic first.
    Custom Chastity’s service is first rate and they communicate! They tell you where you are at as they produce and ship your device. Nice difference.
    I have about a dozen trap ball devices and this is the best designed and most effective.”

    Cheers G.

    I got mine in purple, and i got the grande. I’ve been wearing it off and on for about a month, trying different activities in it, to make sure that i wouldn’t have any issues, once I’m required to wear it 24/7. I’ve exercised strenuously in it, I’ve slept in it, I’ve urinated with a semi-erection it.
    Couple of notes. At least for me and my anatomy, the pee hole is too low. I had to file a slit in the top of the cage, so i could urinate properly, especially in the morning when i have a semi-erection. And I found that getting into the device is easiest with the “stocking method”. When I try just using lubricant, I experience pinching where the top of the cage meets the base ring.

    But it’s lightweight, but strong. I can move freely in it, with no issues. With my slight modification, I’m able to pee standing up. Really, the only time I’m acutely aware that it’s on, is when I attempt to get hard.
    But, it’s definitely a great product. I’ve tried a few off-the-shelf chastity devices, and this one is by far superior in every aspect. I’ve already recommended it to a few people.
    I still wanna play around with the sizes and types, before getting a more expensive one.

    Excellent construction and extremely comfortable to wear. Had issue with the magic lock fitting in the slot, initially (actually broke the key while inserting it). After ordering another lock, I love it! I don’t even know it’s there unless I start to get hard.
