They worked well for me for two years. Then we were updating the closed and called their technician to relocate the system in our house to a different room, and the alarm system started to malfunction. The control main board was then replaced with a new one and their tech was called out again on a paid service call to reprogram it, but refused to do that stating ""it's too much work"" and suggested instead that I should buy a complete new alarm system from them.
