The main thing these have going for them is that they're super cheap. That being said, the 45s aren't the standard diameter, the hole tolerance isn't great, and I doubt the precision of the weights was very high. To their credit, they did hold up fairly well in my garage in terms of rust.

This was the first "real" bar I bought, and it did a decent job. The knurling was fairly passive and the black zinc coating where I gripped it did start to wear off over time. I sold it, but with good maintenance, I don't see why it wouldn't have lasted forever.

This is my preferred attachment for triceps pushdowns. Knurling is passive, like you'd expect. No issues with the product for me!

I use these for biceps curls and narrow-grip lat pull/pushdowns. I haven't experienced any issues with squeaking. Love the heft of the bar.

It gets the job done in a pinch. I don't do a ton of cable movements, but that could be because of the limited equipment. I think that in every way except price a more premium option would be better.

The only certification that really matters. You can get strong as hell here.

For J-cups that came with the rack, I really don't have many gripes. I'll have to get something to cover the exposed portions so that my bar doesn't get worn down at all.

These are good bumpers. At the price I got them a few years ago they were a great value but they've gone up since then (with everything going on). I don't drop them, and they only get used about once a week, but durability has been solid. The tolerance on the hole is great, too.
