This is by far the worst alarm company I have ever dealt with. From day one the panel hasn't worked right. The door sensors will at randomly show open, even though they are still closed. After speaking with the manufacturer of the sensors they informed me that their technicians should have never used the particular sensor on this type of door. After a 2 hr phone call with tech support they finally agree to send out a service tech to replace the sensors for free. The tech Casey comes out without the parts needed to repair the issue. Casey informs us that we will have to buy the sensors to have it repaired. At this point I am tired of all the false alarms and issues so I go buy $120 in parts. I get a hold of the tech to get them installed and he informs me that I will need to call into the tech support number to setup a new service request. Here we are again they want to charge us $59 to come out and fix issues they have caused.
