Review on Quick Release 1 Inch Barbell Clamps - Locking Collar Clips For Standard Bar Weight Plates - Ideal For Fitness Training, Weightlifting, And Bodybuilding By Greententljs by Greg Birchfield

I like them. You push on the handle to open them wide open, push it down to lock them on. Then when ready to remove push once again on the flap handle to open them up all the way holding it wide open as you slide them off. If you do this they won't be hard to put on or take off. But if you just try to slide them on and off without pushing them all the way open they will be a chore to take on and off. Push the collars toward the middle as you close them to make sure the weights are tightly secured. Common sense really. Like the different colors too.
