I've been using the Ring alarm system with the professional monitoring service for a couple of years, and bought additional sensors recently. One of the sensors is a montion sensor and it seems to be defective - the motion sensing coverage is very narrow, around 30 degrees, and I've tried the troubleshooting suggestions found on the Ring app & website (resetting the device, removing & re-registering the device, etc) several times but it made no differences. So I called the Ring community support team to get it replaced, but it appears none of the troubleshooting I've done matters. I explained to the customer service rep what I had done to troubleshoot in detail, but the rep said I'd have to do all the troubleshooting again with him, even if they're exactly the same troubleshooting methods. I have multiple properties and am away from the property that has the Ring system, but took the defective motion sensor with me so I could send it back for a replacement. Unless Ring thinks the customers are not intelligent enough to follow the troubleshooting instructions Ring provides, this is quite ridiculous. Dealing with a defective product is already inconvenient enough. I do understand why Ring would want to make sure all the necessary troubleshooting gets done prior to replacing a product, but having to repeat the same troubleshooting process all over again is **unreasonable** and **unnecessary**. How do you think I was able to measure the motion sensor coverage angle? I've tried above and beyond what Ring instructed for troubleshooting. Avoid buying anything from Ring directly - buy it from Costco or Amazon.
