A good product if you ever "camp" in your model 3. This prevents people from peeping in, and also keeps the annoying sun out if you're a night owl like me and prefer to sleep in a bit. Only very small downsides for me is it would be nice if there was some marking on the 4 sides of it along the lines of (Driver Front, Driver Rear, Pass Front, Pass Rear, would make it a lot quicker to orient when installing it in a cramped area (like your car). Also the suction cups don't fit very well into the grommets, and are a pain to install, would be nice if these came preinstalled. I'll also have to see how well those suction cups hold over several hours, and I'll update my review if it isn't ideal.
