Id only recommend these if using on an axle or ssb with smaller sleeves. They are extremely tight. So tight that it hurts my fingers to even close them 2 yrs later, they never stretched out.

I want to like these more but depending on your bar, they can be a real bitch to clamp down. On my Texas power bar, it's a workout getting them to close. My axle, elitefts ssb, rogue power bar, not a problem. Price wise, I got them on sale, I think 2 pair for either 30 or 40 bucks. The magnetic feature is the best part. Stays on my rack with no issues.

These are ABSOLUTE garbage. I can see if I paid $10 on Amazon, but at the retail price of 4x that? No effing way, capisce? I don’t feel as bad since I got them on sale for $20, but even so. Okay, so they feel cheap out of the box. But the worst part is that they don’t close over a regular barbell. They tighten. But I got them so that they could be used on a loadable dumbbell, since they’re only 1” thick. Well, I wouldn’t trust them since I can’t get them to close fully. I could send them back, I guess. Not sure what I’ll do. But such a disappointment and waste of money.

Nothing special. Does the job. Time will tell if they hold up.

These are a white labeled product, because they are magnetic and have a thin profile, I only use them with these collars with my loadable dumbbells and I haven't had any issues with them (as in the plates don't slide. I also don't drop these dumbbells so the collars haven't been fully tested.

Got these for super cheap from the discount pile at the Bells of Steel store north of Toronto. They are crap. Used them once.

These collars were a gift and are awesome! Some pros are they lock in super tight and have magnets to help store them on your rack and lock in tight against your plates! Although how tight they are could be a bit of a con too. My wife finds them hard to get on and off the bar. I find the best way to do that is by holding the barbell sleeve and rotating it the opposite direction than the lock mechanism and it works great!

I can’t speak to costs and value because I received these as a Christmas present. They will forever live on my rack because the magnetic capability makes storage convenient. An underrated benefit of the magnets, however, is their stick to ability to your iron plates. It will often take a 25 with it when I pull them off the bar. The first couple of uses will require you to use two hands to close it, with one hand on the clip and the send on the barbell sleeve, to crank them away from each other. That or my crush grip sucks. But through many uses, these hold on tight. They may be too good for some bars, but they are a highly recommended addition. Short of the most expensive and calibrated variations, these are top of the line.

For the price they’re pretty good! My one complaint is the clips are really hard to close at first, after a while they wore themselves down on to the point where they close easy now. But they do slip during deadlifts now

Used these at Americas strongest man one year and they did not work well at all. Not much clapping force or surface area so we had adjust them after each set
