I've found two types of roof sun screens for MY. The Tesmania screen is similar to the one sold by Tesla for the Model 3. I have seen discussion on this forum about that one. I also found one on Amazon, by Basenor ,which is a two layer screen. It consists of a dark mesh screen and a lighter, whitish, more reflective screen which can be used in conjunction with the darker one. If you have experience with either screen would you please post your impressions here? Thanks.
