Wow, what a difference the MagneShade made! The dashboard felt cooler almost immediately. We can see out, you can not see in from the outside (except after dark). Installed with magnets only. Does not need a latter to put the cover on the windshield once installed, and only takes a minute or two too put it back up! To visit them click on the link  —>  MagneShade!
