I spent several hours to install Ring. Good luck trying to match door magnets. You have to match each connection based on indent in both connectors. Apparently, if you have a security package, you can ignore scanning bar code but added options required scanning. Very confusing. The instructions are useless. So, be patient and seek on line support. Of course on line chat support is difficult at best. I experienced five minutes between chats. Overall, I will continue to try but first expression is very poor. Keeping boxes to return if needed.
