Chastity device discussions and reviews discussion

I’m contemplating getting a new piece of equipment. However, I’m on a tight budget, so nothing over $50. This has me looking at Chinese options once more. What I need is something for long-term use that’s reasonably comfortable enough to sleep in (or at least not unbearable). Security matters because I self-lock using a realtor box and a chastity android app rather than having someone hold the key, so it’s easy to slip out when pulling away from underwear is as simple as taking them off. I know true security usually comes from a PA, but I’d prefer to leave that choice for a future partner (perhaps a spouse?). Here are two models on my list:

Right now: Amazon knockoff CB600s with KSD. The security isn’t top-tier; without the KSD, I can pull out and put it back in as easily as taking off my underwear. The device makes morning wood quite painful, though the KSD helps a bit but causes some swelling after a day or two. This version has grooved rings (likely to save acrylic for the maker), which tend to pinch skin during the day. Key long-term factors are its closed design and how easy it is to keep clean.
