I'm not sure that those are really suitable for RIBs, as they seem to be rather vulnerable to damage and don't hold drinks all that securely. I have seen them fitted a few times though, so presumably they aren't completely useless!
My choice would be some
XS-IF Coolies
They are soft plastic and attach to any smooth surface (like a console for instance!) using rubber suckers. I thought they sounded a bit Micky Mouse but they work extremely well and are almost indestructible.
