Wholeheartedly agree, I purchased 2. We tried everything too and when we check the battery level we keep seeing this Solar Status "Not Established" god knows how you get it to establish, we've tried it all.
I have the same problem. My Ring 2 recognizes my solar charger because it says established but it is not charging my battery at all. I wanted to give another chance, removed the battery and fully charged it, but I'm still noticing it to be draining slowly. It is completely exposed to the ☀️..... I don't understand! It's frustrating!!!
