Dump fitting wrenches for bad hands

Has anyone used these Camco wrenches? I have a lot of difficulty with the couplings due to a hand problem. They are designed for Rhino-Flex, which I see has identical tabs on both the male and female fittings. My Valterra fittings only have tabs like that on one half. But it is the half that is harder for me to grip. Anyone?



This one could be useful for the CG fitting?
