Very nice product, works well, would purchase again. However the instructions were somewhat off. First my shades came with three mounting points on each shade not two as discussed and shown in the instructions. The question that arises is how to orient the on-off direction of the third mounting point. Two adhesive mounts were thicker and were obviously different than the other four. What position should these be used in (top, middle or bottom)? Why would you need to use the T-mount in the center of the windshield? You instructions need to answer these three questions.
