## Customer Reviews

### ⭐⭐⭐⭐⭐ Worth it if you're serious about fitness
*by J***I on October 13, 2021*

These are a little pricey, but they are worth it. They hold the weight nice and tight and the add another 5.2 pounds to your weight. The only complaint is that the part of the collar that clamps down is smooth which can cause it to slide on the bar. To remedy this I took some padded rubber and neoprene blend tape and applied it the the internal clamp mechanism. This made it fit very tightly and it no longer slides. I love these for my heavy lifts and it makes the whole bar feel more secure. Recommend if you not just a casual lifter.

### ⭐⭐⭐⭐ Use rubber-coated plates to make these collars stay tight.
*by D***V on April 3, 2021*

These are SUPER HEAVY DUTY. Thats what I liked about them the most and the reason why I didn't return them. I was going to return them because I constantly had to re-tighten them after every deadlift. I am not the type to drop my weights. When I deadlift, I place my weights down after every repetition, so the loosening did not occur because of dropping my weights. It was a hassle having to re-tighten over and over but I figured out a way around this. I used a rubber-coated weight plate at the ends and this was the only way these collars stayed put. When I had uncoated steel plates at the end, this is when the collars would loosen. I'm glad I figured a way to keep them tight because I didn't want to return these heavy-duty collars.

### ⭐⭐⭐⭐⭐ Best steel collar on the market
*by A***R on February 4, 2021*

Amazing product, use regularly. wont slip when deadlifting
