Although it is slightly more expensive than others but good quality and customer service is good! Thanks for the patience in answering all my questions. The technician that came to my house is friendly and solved my problem. Keep it up, GTC team!
Purchased house alarm a few years ago. Due to heavy rain alarm system got stroke by lightning and had to repair. Poor service and not customer oriented. Often cancel appts last minute. Customers have to follow up instead. Once sent someone to replace mother board chip however only to find out he is not a tech and someone from the office. Coudn't care less even cutomer complains. Expensive and not reliable. Not value for money.
