Works great and lowers car temp significantly (I also have tinted windows). Really good lampshade design and it folds up quickly when not in use. One of the issues why I gave it 4 stars is that it doesn't fit perfectly. You REALLY need to press the sunshade into the base of the window for it to fit properly so you can lower the mirrors to secure the sunshade. I have never had to do this on any other car I've had with a different 'matched' shade in the past.
