Since I used this style of rubber/gripper plates for years for bodybuilding training in commercial gyms, they were my first choicefor the gym, for convenience, loading, deloading barbells and machines, quiet for my penthouse apartment, but also they are very useful as a tool, we use them by their grips for many strength exercises/movements.
I am happy quality-wise, but quite expenssive for getting in my country 2 full sets of them.
