Last summer, I had Generator Power Systems install my generator. The installation and such was conducted by very knowledgeable people. After several power outages, the generator has worked perfectly. I no longer worry about storms cutting off our electricity. It was a very good investment. The best part, is when my neighbors call during a storm and ask if I have power. My response is, "Sure do, my generator is running." haha I'm going to be really popular when the next hurricane blows thru and knocks out power for days if not weeks. Thanks GPS!
