Quantum employees! Please stop posting on this or other websites. It's hard for me to imagine how one could have positive experiences with this or ANY other alarm company that has 3yr contract. Whole industry is shady and a total rip-off.
People, grow-up. Install a system on your own (it's not that hard) and self-monitor or otherwise there are reputable companies that don't install your system for free but charge less than $9 per month to monitor an existing system. A state of the art system (not the crap these guys install), costs less than $600 for a large house 2500-3000 sq ft. if you can install yourself.
Pros: Of-Course none
Cons: Everything
