If a whole lot of weight comes down on the floor fast, these will still shift a little bit, which is a little irritating (like I said, I'm fussy). But there's zero chance that they're actually going to allow the weight to come off -- or really, even shift more than about a quarter of an inch over the course of a set.
I'm pretty sure that as long as I'm staying below about 35 pounds per side, I can even do exercises that involve having the barbell perpendicular to the floor (e.g., the barbell side press) without any sliding around. They grip pretty tight once the red tab engages. (I should note that the enclosed instructions say that one should NOT do this, but I suspect that's legal CYA, not the actual limits of the product.)
The red tab, BTW, isn't really a "lock." If you pull up on the black cam, it will open without having to disengage the red tab separately. The red tab provides just enough extra 'pinch' to keep the rubber pads compressed, which is really the key to the whole mechanism working effectively. The non-pro variant of this collar doesn't keep them under as much tension, I would guess, and so they would tend to slide around more.
We use these with bumper weights on quality bars. There is definitely slipping when dropping from overhead or when dropping from anywhere with weights above 250-275lbs. It is manageable and better than just a spring-clip, but readjusting is still a requirement most of the time.
Next time I think I'll try the aluminum OSO collars to see if they are any better, but these get the job done day-to-day.
I have been dealing with a thumb injury and these are great. You just unclip them, slide them on and them snap them shut.
If you are thinking about these order them now, you won't be dissapointed.
Do note that the weights can wiggle a little a big after many repeated drops. This mostly happens after dropping the weight from shoulder height after a clean movement. Still infinitely better than those wirey metal clips lying around at the gym.
