I had the guys over at iHummingbird come by my home and install a doorbell with customer rings and a nest camera for me. The installers were very nice and professional and once they were done, they showed me how to use all of it. They were very patient in answering my questions and showed me a couple of times how each thing worked. These guys were just very courteous and good people and I really appreciated their explanations and demonstrations. Their prices are great for what you get and I would definitely recommend them to everyone!
