Short pros and cons: + Easy to unfold and install + Blocks a lot of sunlight + Strong velcro straps + Suitable for large phones including my Galaxy S21++ Study, won't fall apart in the wind. + Fits easily in the inner pocket of the Fly More combo bag. Difficult to fold back. Difficult to insert into the controller when the phone is installed. The USB slot is very small and difficult to insert a cable. Incomprehensible instructions - Strange viewing angles - Weak top magnets. Umbrellas are especially useful during the day when most people are flying their drones. This helps reduce glare, allows you to dim the screen's brightness a bit, and improves your ability to see what's happening on the screen. I have a Galaxy S21+ phone and yes it fits and does the job pretty well but it's a huge pain. Deploying and assembling is quite simple and straightforward. The clasp is very strong and will not come loose even with a light gust of wind. Trying to get it into the controller is another problem. There is a bottom part that is. nice, but also not? This is very difficult compared to other types that simply attach to the antenna assembly. Trying to connect your phone to a USB cable is a big hassle. Since you have to put the sun visor on before you put the phone in, you have to thread it through a tiny slit on the side. All in all it takes me 5 to 10 minutes to put my phone on it and connect it to the controller. As for ease of use? If umbrellas are meant to block the light, they do pretty well, but not in the way you'd like. It's hard to look at the screen! The top is foldable, which means you have to look at it from a very odd angle. You can fold it up with a weak magnet to keep it in place, but it still doesn't offer great visibility. The compilation is also a big problem. The instructions tell you how to unfold, not refold. I think this would be a good option if you want everything to be fully covered, including the ground, but I don't recommend a sun visor when there are so many other things. options on the market. It does the job, it's very easy to learn but it's mitigated by how difficult it is to use. I keep it but can't bring myself to recommend it.
