The workers at iHummingbird are very informative, helpful, and professional! I initially only ordered a thermostat from them, but when the technician arrived, he explained the various other products their company had to offer. He did a great job explaining and really sold some of their other systems! We are now considering a few more products they have, such as the WiFi controlled sound system. They are a very good service that we look forward to doing further business with!
