I got the first solar charger in May. After a whole month spent going through all the posts related to solar panel failure and not getting it to work, I contacted support. I was sent a replacement solar charger that worked for ONE day and then stopped charging. At this point I was fed up and wanted to return everything and go with another vendor. Ring support informed me that the return window is 30 days. This is a seriously defective product and I am going to throw it in the trash. Do NOT buy anything from Ring. They have quality issues and ther are other vendors out there with superior products.
