Pros: #1 I ran some tests and the dash actually cools down about 10-15 degrees compared to my previous $12 version, that I bought from a big seller. . I have held and compared several temps over several days. About 55 degrees colder than without a reflector. See pic #2. It's easier to install than the cheaper version because it's stronger and fits better. Cons: #1 is more expensive than #2 doesn't quite fit. I want it to fit snugly around the edges and top around the camera. Has about 2-3 inches uncovered on each side. See the figure for the data points I collected. I am not recommending any product, I am only providing data that I have made for myself. * Please note that my windows are NOT tinted. I have a 2018 Honda Accord.
