Query: Great system for the money (even larger homes)

After reading several reviews, I settled on this product. My fear was it wouldn't work for my 3000 + sq ft home. All the info said it's great for apartments and small homes. I bought extra motion, door sensors, window stickers, and an extra key pad. I've gradually added more items as time/$ allows. Overall I'm very happy for the added peace of mind for a reasonable cost. At the very least it might be a deterrent. It was easy to set up and add other components later. My tip is keep the main unit in a central location to limit the distance from the different sensors. I do wish I could have a few more choices for which sensors are armed/on delay/off. Some of the different arming sequences are not intuitive and tough to remember, but the basic arm/disarm is easy.
