I recently completed seven weeks locked (mostly 24/7) in a Male Chastity Now Contender with the PA upgrade. My previous experience includes a CB6000S, Holy Trainer, Birdlocked, and several cheap 'off the shelf' metal cages. However, this is far and away my best device. The MCN Contender is a custom metal open cage ball trap device, and can be ordered with or without the PA upgrade. The benefits: - The Contender is unbelievably light for a metal cage - I found virtually no difference in weight with my plastic devices - As it's custom made, it is extremely comfortable. It fitted me perfectly. I was able to sleep all the way through most nights. - Cleaning is so easy in the shower because of the open cage design - With the PA upgrade it is extremely secure - there was no prospect of pulling out - It can be ordered with a secure emergency key, which is a great option as a spare if (like me) you don't live with your KH - MCN's customer service is outstanding (more on this below) The drawbacks: I am being honest when I say I didn't find any major drawbacks. - On the rare occasions I was briefly unlocked the key and security screws needed some patience to align but my KH and I got better at this with practice - The PA upgrade lock rubbed slightly on my balls - but that was eased by using plenty of moisturiser and sometimes I placed a small tissue pad underneath the lock. Wearing close fitting underpants also helped minimise rubbing. - I am uncut and (after about three weeks) I got a tiny amount of swelling in my foreskin near the piercing, but it was not painful and disappeared within 24 hours of being unlocked. The other huge plus for MCN is how responsive the company is. The owner Mark responded to my emails often within a day and once I'd placed my final order, my device was built and shipped within a week. I live in the UK and paid extra for express air freight, and it got from Seattle USA to my home in 48 hours! I feel I wasted so much money over the years on mass produced 'off the shelf' devices, being disappointed time after time with the poor fit and security, it has been great to find a secure device that I could wear 24/7 for such an extended period. I finally started to discover what chastity veterans report about the 'high' of extended periods locked up. Quite simply the Contender is a fantastic cage. As with any custom device it is more expensive, but in my opinion worth every penny/cent. If you are looking for a custom cage, especially if you have a PA, I would highly recommend checking out MCN's website.
