I love the whole concept of the Interlock System and the whole setup was fairly simple for me to do... although it's recommended to have an electrician install it for you. I finished the install yesterday and tested it today. I connected my 7500W Generator and it powered almost the entire house. I have mostly gas appliances so the load is much less. However, I was even able to run the Central A/C. The whole system cost me around $300. I know an electrician that offered to do the install for $650. All things considered, I prefer this to either an Inline System or a Transfer Switch. For me, this just makes more sense. Didn't do it in time for the freeze but, where I live, I'm pretty much guaranteed a couple of big power outages each year.
