Just installed a factory refurbished Simplisafe system in my mother-in-law's house last weekend, and I must say that I was blown away at the value, engineering, and capabilities of this system! I started with the full premium monitoring package for $24.99/month and I got everything I wanted and more! The system lets ME DECIDE what doors and motion sensors I want to monitor myself vs those that sound an alarm and go to the monitoring center. I have motion sensors and interior doors that I monitor even when the system is disarmed so I know when she is active and moving throughout the house. I can review this activity daily and know that she is OK. Everything is so configurable and programmable and everything can be done from a keypad locally or anywhere from my mobile phone app. I have not found a single feature yet that I need that is not supported. It is almost like Simplisafe actually tested used this product before selling it. Hard to believe, I know, but the engineering team on this one deserves a big bonus and a pat on the back. Since the app supports multiple locations I am going to get a system for my work and my own mom next. Nice job Simplisafe !!!!
