I purchased this product a couple of weeks ago. By the way, the customer service was amazing! I have used it for over one week, and it is flawless. Amazingly easy to install. It absolutely deserves the five-star rating!
Only have one wish: Perhaps Infinity Shield could offer a wireless red light that you can place in the front of the garage to signal STOP? I am considering hacking into the device's audible alert to signal a light using an Aqara door sensor that would do this. But if they just sold it, I would just buy it.
Great job Infinity Shield.
