Hi. I ordered the item for someone not myself cannot give you a review only that full filling and shipping the item was fast

Although they look good and look functional, there are 3 things that left me unsatisfied and if I knew I wouldn't have made the purchase. The 3 things are:
The first, and for me the most important, is that because I wear medical glasses, with progressive lenses because I have astigmatism and farsightedness, I can't use GL1 because my face with my glasses doesn't fit (see attached video - https://youtu.be/QXaOckLKslc ) . A serious flaw of your Designer in my humble opinion;
- The second, it is planned to place part of the GL1 on the Radio Controller support, for which you include a piece and screw for that. But that doesn't work, because after tightening the screw all the way, the GL1 are loose (see attached video - https://youtu.be/QXaOckLKslc );
- The third refers to the poor insulation of light in the interior. That is, in an environment of intense sunlight, with the GL1 placed, it is more difficult to view the images projected on the screen due to excessive light, forcing us to increase the degree of brightness and contrast of the screen, with consequent consumption in excess of battery, and loss of quality in the image to be viewed, (see attached video - https://youtu.be/QXaOckLKslc ).
In short, it is a product with a good price / quality ratio, but …….. there could have been better attention to details of great importance, especially the first one I mentioned, that is, those who wear conventional glasses cannot use these GL1.
