I bought the two smallest cages in this line.. I have owned in past many different ones that never worked right. I always accidentally came out of them as one of my testicals are a bit on the small side. In the past the Holy Trainer was my only success until now. These Jeusn cages are much more comfortable and so far I have not come out. I am a full time (24/7) user. My wife is my key holder. Being full time in chastity I require a comfortable and practical cage. This (so far) is perfect. Love my choice on this purchase. I would highly recommend.
