The Futuristic Moon Explorer (right) is clearly copied from the Linda version of the MEV2 (centre), which is shaped differently and is larger than the Spacex original (left). But whereas the Linda version has wheels with curved spokes as per the Spacex original, the Futuristic version has straight spokes. The grab-arm on the Futuristic toy is made in one piece so can't be articulated as it can on the older two toys.
