The sales person came to my home right after my late afternoon call and explained the offerings in detail. I was impressed with his comprehensive experience and personable presentation. When I decided to have the system installed, he booked an installation for me the next day.
The installer was not able to make the estimated time because of an earlier job that ran over. He stayed in touch with me and I was fine with waiting. He arrived then at the end of the work day and accomplished the entire installation deliberately and carefully over several hours. Some of the windows presented problems that he solved skillfully. He explained the system workings and walked me through them, even though it was quite late by the time he was able to leave. The company had wanted to fit me in so soon because my request was based on a disturbing incident at my home the day before.
The next morning I received a call from the office, checking on whether I had any questions and inviting me to call if any came up. Some probably will come up as the system, probably like all of them, is complex. It is not at all difficult to use, however, through the console, online, and by smart phone. I am able to designate family members to back up my control of the system and to receive response calls if I do not answer.
