This has been my EDC for quite a while
I'd been using S-biners for quite a few years between my car fob and my keyring so I can separate them. First I used one of the original smallish ones, but after a year or two, the spring sagged, and the keyring would randomly fall off. No problem, I bought a 2 pack, I replaced it, good to go. A year or so later, I noticed the spring sagged again, but I had not yet replaced it. Anyway, I was at a restaurant after a golf day, and I had stuffed my keys in my hoodie after the round. I realized this, literally as I was having a stand-up in the bathroom, reached into my hoodie to move it to my pants pocket, grabbed the fob, and my keyring separated flew through the air, directly into the toilet perfect timing as it was flushing. And yes I reached my hand into a public toilet, but they were gone! I walked out of the bathroom, my golf friends asked what was wrong, I looked stunned. Thank goodness, I still had the fob so I could drive home! The next day, I was back on Nite Ize site, and they had invented the MicroLock Mini. A couple of days later I locked my keys, no problems for five years! Other reviews express frustration that the lock is a fiddlely, but I figure the valet or whatever can wait a fuxxing second, at least I don't have to worry about reaching into public toilet toilet in the future!
