I recently installed and been using it for sometime now. The setup was easy, it took around 4 to 5 mins for the camera to recognize it and show that its installed.Since installation, it has kept my cameras consistently charged, but its not cloudy much these days so I'm wondering about how well will it works on continues cloudy days. I'm happy that finally I'm not bringing my ladder and need to frequent battery changes and ensures uninterrupted monitoring. Plus, it comes at a great price, making it an excellent value.Overall, it works great and maintaining my ring cameras charged with sustainable energy. Highly recommended!
