Works well.
Just ordered a few days ago, but the one time I used it, it worked pretty well. Seemed to dry within hours. But I'm writing so early after purchase to clarify a problem some people have mentioned. The bottle, without the cap, is pretty big. Roughly 1x2x3, which would be ~100mL. So you're buying 50mL in a 100mL bottle. It's going to be half-full. This probably helps with shipping and pressure/leaking issues.

Works well
Perhaps too well? I stripped a tiny bolt today trying to get it out that had a drop of this put on last week. I got some on the bevel of the screw and it welded itself to the nylon but I was able to get the lock to break without heat. Just need to use a drop. 50ML is probably a similar size to elmors glue. Bugger than I expected. This is what id want on my toolbox, not in a go bag. Great price for the volume and it works.

Exactly what you expect. 10/10
I bought this to secure my red dot sight, as every time I mag dump, my accessories end up flying off. This works perfectly and now my red dot is secure thru extended mag dumps... Now I just need to find a way to secure my cheap chinese laser 🤣😅. 10/10 thread lock, does exactly what you want it too

Imperative that you use this on disc brake bolts
This blue locker is considered medium, in that it should hold a bolt, nut, or anything with a thread in place, but still allow removal. I was forced to get this after my disc brake bolts loosened, causing it to protrude and carve an indention in the soft aluminum dropout of my Fox 32 suspension fork. This product will keep the bolts in place, and as a mountain biker, I don't want you to make the same mistake of tightening your disc brake bolts without a locker.
