Ray was super knowledgeable, friendly, and proficient. He did not try and upsell me on his products, and only provided us with what we needed to monitor and protect our home. I like to have a thorough understanding of things that I purchase, especially if I'm spending a lot of money; I asked Ray SOOO MANY questions and he made me feel comfortable when I did and answered them with patience. The temperature was so cold outside that he had to come over several days but he was determined to get the job done. His price was very reasonable as well. Thanks Ray for a great job and we are thankful to have peace of mind and better sleep.
