Well first off for those that don't know, you need a compustar alarm system installed, and then you need to add a $300 module (which uses at&t's crappy network) to make this work. Which is fine, their alarms rock. But, for $300 for the module and $30-$300/year, I thought the bugs would have been worked out by now. But no. I've had it for quite sometime now and have only had a few successful uses out of it. There's always either a connection error or a log-in error for whatever reason. But, once the bugs are gone, this could be a 4-5 star system. Def. Recommend trying it. G/l everyone.
