Chastity device reviews discussion

I bought a Holy Trainer v2 device last week. It’s black, features a short tube and a 40 mm ring. The build quality is good and it feels quite comfortable—no issues with the locking mechanism or similar aspects so far. However, security isn’t perfect. I can’t remove it entirely because the gap between the sheath and ring keeps my testicles from slipping out, but pulling the shaft in and out of the sheath is very easy. My unit has a small cage paired with that 40mm ring. Following the measurement method on the Holy Trainer website suggests the 40mm size should be correct per their instructions. Yet, I can slip the ring over easily; this might mean it’s actually too big—when worn without the tube attached, I can fit two or even three fingers (not thumbs) underneath. With everything locked tight, the sheath length seems fine, but the entire unit sits a bit low, sliding downward slightly. There’s ample space between my scrotum and the back edge of the tube. Even if I switch to a smaller 36mm ring, I doubt it would solve much since 4 mm doesn’t seem like enough difference. I’ve worn it day and night without issue and haven’t masturbated, but knowing I can cheat whenever I want undermines the whole point of chastity for me. My wife is also uneasy because she knows I could go about a week without an orgasm even with no device on board afterward—so that guarantee isn’t solid. Today brought another headache: the entire unit slipped off in the shower after one testicle managed to squeeze through the gap, confirming my suspicion about the ring size being too large. I plan emailing the manufacturer for advice. I also suspect a silicone ring placed between the A-ring and sheath could tighten up the construction and resolve those security concerns.
