Query: No good in summer

Was happy initially - suction cups good, aesthetically pleasing, easy to move to another car.... was using it for my neighorhod transponder (gated community) My car is garaged and I always use a sun shade in parking lots. however, one summer day the black plastic melted and the holder fell from the suction cups (which remained on windshield). I almost crashed into the gates when they didnt open because the transponder was on my floor. Then I almost got rearended trying to back away from the gates and use the visitor entrance. disappointing.
