The technicians are extremely professional, friendly, on-time and quick on the job. Our Condo building uses them for the intercom system and garage alarms. HIGHLY RECOMMENDED.
Pros : The technical people, they are helpful, explain the issue very clearly over the phone, and arrive at your house on time. (we had the first appointment of the day)
Cons : The receptionist seemed to get frustrated with me over the phone, but she was trying to be nice. Suggestion, stick with talking to the technical people about your inquiry.
