I've been using the Sun Shade for a while but yesterday I forgot to put it in the window. It had to have been at least 20 degrees hotter in the car. On previous days, it was cooler in the car than outside on the blacktop parking lot. So yes it works well in Dallas sun. I have heavy tinting on the rest of the windows so the windshield is the major heat source.
