I had an opportunity to use Jet Shades on the way home to FL. Since we departed Sunday morning, the sun was directly on me and was a little hard to see the instrument panel. I put the Jet-shade in the pilot window and it was very dramatic. The glare was gone on the panel, and it wasn’t hot anymore on me. I don’t have any financial stake in the company, so this report is just what I saw. I do recommend them highly so far.
