Title: Never worked properly
Review: I had also ordered a second transmitter. The garage doors are about 30 feet from receiver. On the first day or two it registered properly. After that, the receiver would alternate between the door(s) opened or closed. The red and green lights would alternate. Even when it worked properly, within a few hours it was confused and started alternating red and greed lights. I tried removing one of the transmitters and even changed batteries. No remedy worked and I finally removed the entire system. Unfortunately I am outside of the return window. I would NOT recommend this product.
