Love this roof shade! Installed it alone after watching a video. Immediately could tell the difference in temperature. I did not install the magnets as the slight sag was only noticeable to those riding in the back seat. I honestly never noticed it! Now that it is cooler, I removed it today. Sadly while trying to twist/fold to out in the storage bag, the frame broke! So just know this is not the bendable wire that most smaller shades have, this frame is a breakable plastic! Decided to just place it flat under a bed till spring. Hopefully I can get it to fit back in place and stay when I replace it next spring! Love this company and have ordered many accessories from them and always been pleased! This is the only issue I’ve had with any of their products.
