I am so pleased with Lorrie & Brad of Owl-Tech, extremely professional, helpful & upfront about what will & will not work. Have dealt with this company since it's beginning & with the owners long before. I have always had great service at a reasonable price. While stating a price would not be fair since every situation is different & the wants/ needs are also so different, but suffice to say they are more than reasonable. Monitoring is very beneficial & reassuring. I have had my system for sometime now & had very few difficulties, the few I did have were dealt with quickly & efficiently.
