Another one for SimpliSafe. Only had it about a month. Since we didn't have any system before, there's some getting used to it which would be true for any security system.
Part of my job is user friendly design. I can say that SimpliSafe actually did a pretty good job with their setup process and user interface. it's not perfect but quite good.
As long as you can read [simple] directions and folow them, you can set up a SimpliSafe system. If you're the type that thinks that changing a flat tire is horribly complex, I'd go with someone else.
I need to get some ADT yard signs too, since I believe in deterrence, but not tipping your hand as to what you have! :)

CrewDog, since you're in the 'springs, if you have more questions I'd be happy to meet up (Whistling Pines West?) and answer them face to face. I could show you their smartphone and web interface, too. PM me if so.

Ps. Had one defective motion sensor. They're exchanging it, no problem.
PPs. They give a 10% discount if you get a referral. I'm sure that Dave_L or I would be glad to give you a referral (we'd get a month free of monitoring too)! :)
