I bought my first house and live alone, so a security system was high on the list. After looking at a few companies, FrontPoint seemed like the obvious choice.
I've had the system for several months now with no problems. Set up really was THAT easy. Just stick things to windows, doors, walls, etc.
Customer service is wonderful, and my favorite part is the smartphone app to let you set your system remotely (for those days when you leave the house and forget). It's also great for "checking in" while you're gone to see that all the doors and windows are still closed.
I've recommended the system to several friends and wouldn't hesitate to keep doing so.
