Perfect Olympic Dumbbell spring collars. Nice action.

It does the job

Easy to use

These are basic spun metal spring clips. They are easier than I was expecting to compress and use. They do hold on my barbell and equipment, just not with a lot of force. The downside of not being spun tighter, to have more clamping force, is that they don't fit on my weight tree. That was going to be my main use for them, but they just don't clamp tight enough to hold on to slightly undersized weight storage horns. If you have a proper sized bar and want something that's easy to compress, these will work fine. If you're lifting heavy and want something that will hold a lot of weight back, I don't know if I'd trust them.

It holds fast. But was not tested vigorously
