I saw these glasses in an advertisement and thought they would be just what I'm looking for. The sun here is pretty bright and I can't always see my ipad even with sunshade and a screen cover. Even when I can, when I look at the ipad and look back up, many times I can't find my drone in the sky without taking it higher or performing an RTH. I've read everything I can find on them and most of the problems I've seen are heat related and it does get warm here during the summer especially. Does the 2019 version have heating problems or any other problems that may make me regret a decision to buy them. They really do seem to be a great alternative.
