Rated 5 out of 5 by from Great buy I had old collars difficult to open and to move on the bar, it was long and tedious to change plates. Now it’s quick and easy, even outside when it’s freezing

Rated 4 out of 5 by from Good grip, price is right They are metal and give a good clink on my concrete slab. I saw some people complained they were hard to use - you do have to use 2 hands to close them, but I did not have trouble using them the first day and am better / more used to them now. When you press them all the way down they hold very tight. They can be a bit tricky to slide down the bar even when compared to other types, but these are still good for the price. I'm happy with them, use them 3-4 times a week, and have no plans to upgrade.

Rated 5 out of 5 by from Good collars! About 7 steps up from the spring collars I was using beforehand!

Rated 5 out of 5 by from Sweet Collars Easy to use and they stay where you put them. Way better than those janky old spring clips.
