RING! I bought 3 of these for 3 Ring 2 Doorbells solar panels and NONE of the 3 work. I have tried all of your irrevelant fixes (Make sure it gets sun, re-install, clean connections, etc) and NONE of the 3 work. That is statistically significant and cleary indicated RING is selling a product it should know does not work reliably. Your solar panel appears to be a scam but definitely a product that does not work relaibably. Here is the products reviews and comments on Amazon and you will see even though you probably already know this product does not work reliably or as intended. These reviews go back more than a year so thank you RING for scamming the public. Google Solar Panel does not work for Ring 2 and the number of people that indicate this experience is vast. It is unfortunate that you feel the need to take advantage of the public.
