        A couple of the individual weights have been damaged, can I buy the weights separately?

      • Q:

        Please help. I've owned the adjustable dumbbells for about two years. The left dumbbell no longer adjusts - the turning mechanism is locked. I can still take the dumbbell apart if I place it on the floor, turn it upside down, and hit the button, but obviously that process defeats the purpose of these weights. Any idea how I can repair?
