Glad to hear I’m not the only one…
They have various types, the Neo has the “slide lock”. It’s a plastic thing made of two parts: one side is the slide lock that you need to pop off with your fingers (top picture), and the other side is the thing that goes into the holes in the strap (bottom picture). Remove slide lock, remove other side, move it to desired length, reinsert slide lock.
Unfortunately the “remove slide lock” and “reinsert slide lock” parts (in my case at least) took around 5-10 minutes each, because they’re so hard to slide in and out. My fingers were hurting and had cuts on them by the time I finished. (I didn’t want to use a plier, because I’m certain it would break the plastic.) Then a couple of days later I noticed that one of the slide locks was missing, and found it lying on the floor… I assume I was not able to fully slide it back the first time.
Check out the below video where they show how it works. You can see him adjusting a slide lock at 3:20, and another one at 6:20. The one at 3:20 works easily, but at 6:30 you can see him starting to struggle with the 2nd lock, and then the video cuts to the future where the lock is magically open. That’s the part where you spend minutes trying to get the f.ing thing off.
