OwnZone Olympic Barbell Clamps, Quick Release Non-Slip Barbell Collars Clips for 2-Inch Olympic Weight Bar Plate, Lockdown Workout Weightlifting Fitness Training (2 Pair/4PCS)

Works perfectly and does not slide

Fits great and works great.

Great product for a great price.

The clamps were easy to use, very light, have great color and have held up well. However, one of the clamps is showing signs of lossening and not clamping onto the bar as tight as the others. The rubber inlays do help with the gripon the bar. To be clear these are plastic clamps.

Good product

Broke within a year of having them. You get what you pay for. I suggest buying the more expensive ones with a warranty.

For the money they aren’t bad but that opinion might change depending on longevity. Used them for a week so far and they work well and are quick but one is loosening up already. Would be nice if they opened all the way so they didn’t have to slide off the bar but with most lifts these are near the end of the bar anyway so it’s no big deal. Would have to be made of metal to really feel great and of course that would drive the price up significantly. The clips that hold them closed will probably be the first thing to go. Good overall but a 4 because of lack of consistency in quality and fit.

These things are delicate to say the least. They hold well and all once in place, but the release tab on one of the clamps broke off the first time I had used it. I bought the 4-pack and am glad I tried each pair out to identify the weak one. I wasn't doing anything out of the ordinary and have used these a thousand times at the gym, so I was surprised one failed so easily. It got me questioning the quality of all of them so I ended up returning the product. I hate to give them 1-star, as 3 worked fine, but I'm not sure for how long.
