It's definitely made a difference - I no longer return to find my car suffocatingly hot and my steering will impossible to touch because it's burning. I do wish the windscreen cover was a little bigger in size. I flip back the sun visors to hold it up against the windscreen and it only just fits without slipping out.

compact and easy to store, however doesnt stay up against the windscreen for my car and just lays on the dashboard instead.

Great for the hot days as well as privacy.

It is too small doesn’t fit the windscreen. Still waiting for a bigger one.

I like that it blocks the sun.
Wish it was maybe slightly heavier to really keep put the heat from the car.
But overall i like it protects my car from heat
