It took me a hell of a long time to figure it out at first, but once I got over my frustration (and really looked at tiny directions) it all came together nicely . I use it for my DJI MAVIC AIR 2's controller. It doesn't look elegant, but it definitely protects the phone well from the sun! I was going to give four stars just because I can't (and still haven't figured out) how to fold back properly, but why take off a star for my own ignorance? I folded it well enough to reattach the strap. I would recommend this, it's a very good quality shade for a whopping $20.
