DMoose Barbell Clamps

They don't appear to be durable for barbell use. Use on my machines.

Magnetized is why I bought them. Work fine for basic barbell movements. But I would not recommend them for dropping barbells.

They are magnetized, which is cool. They don’t appear to be very durable and I don’t anticipate they will last long. Spend the money for better collars.

I only use these on my curl bar now because this cannot handle any serious weight. They cracked after 30 uses and were incredibly stiff before that. Just buy the bells of steel if going cheap or upgrade to something that won’t last only a month

I have a few of these, largely because they're cheap. I leave them on various machines. They can be loose, and I use better collars for actual barbell lifting, but as inexpensive items that I can have a bunch of so I'm not always searching them out for every machine, they get the job done.

Use these for my plate loaded machines and for that, they work well. Wouldn’t use them for any real lifting and they shift on stuff like deadlifts. Cheap enough to buy for each machine and leave them there because they have magnets. Use case wise, that’s probably all they’re good for.

Let’s be honest, there are a ton of these rebranded for various sellers. Regardless, they work okay. They are magnetized which allows them to stick anywhere on your rack. They come in a ton of colors. They work well enough. These are not my go to collars, primarily because I find them too thin to really comfortably release and all. They are fine, just not my first choice.

I have the magnetized version of these and use them quite frequently for plate loaded machines and EZ bar curls. They are mostly plastic and the build quality isn't as robust or beefy as some other collars on the market, but I've never had an issue with mine. They snap into place and hold the weight there and the magnets are a nice feature that allow them to be stored virtually anywhere. Not sure I would trust them with a ton of weight on each side, but for the price they are fine for what they are. I'd recommend them for EZ bar or specialty bar curls where the sleeve is smaller since these are very narrow and definitely better than spring collars.

At least they come in colors, but they would not be anywhere near my first choice for a collar. They can be loose at times. I try to use them in low stress areas. I would not buy them again.

Not a very good hold, I would not buy them again. Sitting on the shelf
