system sold to me in 2016 no one ever returned to install the small boxes to windows and doors. Multiple calls with promise of someone to come and to send me info on how to reset control module - NEVER HAPPENED.
Customer service person stated she would send me when contract was up so I could stop their product NEVER HAPPENED. My advice FIND SOMEONE TO PROTECT YOU NOT JUST TAKE YOUR MONEY LIKE THIS COMPANY WITH NO SERVICE AND NO FOLLOW THROUGH ON WHAT THEY SAY THEY WILL DO.
