Bests & Worsts Reviews from Amazon

Great concept, but not very reliable, as a security system should be. I've had for 3 months now (past the return period) and 5 times already the text and email alerts have stopped working for couple days at a time. Apparently they sub out these alerts to some company that isn't very reliable. Couple of the times I called to complain, they "gave" me a free month of service, 1st time I had to call back a week later to actually get them to honor that. 2nd time they promised the free month... they still haven't honored it, I emailed and they said "the issue should be resolved now", and still ignored where I said they still owe me the 2nd free month they promised, so I emailed them again, we'll see, maybe I'll have to do a credit card chargeback. But the money isn't the issue, the issue is the apparent non-reliability of their "security" system, and they're lying about crediting me, and still ignoring the 2nd time I brought up.
