Here's my take on the glarestomper sun shade...
The glarestomper arrives in a flat postal envelope slightly larger and thicker than a standard letter. It contains the shade, a thin strip of adhesive Velcro and installation instructions:
The shade is made of thin foam sandwiched between fabric and edged with nylon webbing. Small strips of Velcro are stitched on it at appropriate spots
This is the size of the unfolded shade compared to my iPhone 5s. It will fit any phone up to 5.5" according to the instructions:
The adhesive Velcro is intended to be stuck around the edge of the device that will "wear" the shade. I don't plan to do that to my phone, so I had to find an alternative. Here's my solution:
Hold the shade in place with the Velcro strip attached to one side of the shade like so:
... and pull the strip tightly around the phone to the other side, fastening it to the opposite Velcro strip:
Once that's done, it can be inserted into the clip on the controller quite easily, and the clip then holds both the top of the shade and the Velcro strip tightly to the phone:
The last adjustment is to make corners at the appropriate spots on the front. There's actually a strip of bendy wire sewn into the edging on that side, so the corners will hold their shape:
Once that's done, you're ready to fly.
The shade is deep relative to the phone, so I expect it to provide excellent shade:
The one modification that I plan to make will be to stick cloth or possibly something rubbery to the Velcro strip's adhesive and cut it to the exact size that I need. In a perfect world, the strip would be elastic, but I expect it to work fine as-is.
My first reaction when I opened the package was " wow, this is pretty flimsy for $17." Having gotten it in place though, I'm very happy to have found a lightweight, apparently durable solution to my glare problem.
