The technical staff called me back right away, they were knowledgeable,had a professional demeanor, and provided outstanding customer service. I recommend to women that they purchase a wireless alarm system because they can easily install it themselves and any questions they have can be answered by the experts at Smarthome. Once you are guided through a flow chart the process of programming it is a piece of cake. All owners of an alarm need to know how to program it to their satisfaction in order to secure your home properly. When I told the staff at Smarthome an item did not have a battery they shipped it right away. Thank Smarthome
