So Relieved and Happy
Would RecommendRunning now for a year. We have had power outages while away. It was great not worrying about the basement flooding. We have also had a couple long term outages and it's nice not having to pull out our gas one and set it up. We didn't go for the whole home. We have our furnace, well, sump pump, septic, freezer room, kitchen fridge and some outlets. We also have my aquariums running on a circuit. Well worth the money

Great investment
Would RecommendHad this installed about a month ago and a couple of weeks later it worked as designed during a short power outage. We have peace of mind for the upcoming hurricane season.

Ready when!
Would RecommendI've owned this unit for over a year now and it was purchased through Costco. It has kept the power on a few times for short outages, without fail. No hurricanes yet and hopefully we won't have any, but, I'm ready if when we do.

Mostly happy
Bought this a year ago, we are happy with the system itself but not with the company who installed it, we were pushed to buy it and then their follow up has been no contact at all, they got their money so they don't care

Well engineered and assembled!
Would RecommendAlthough I have just had this unit installed a month or so ago, my wife and I are so happy of knowing that we will have power when there is an outage. The cool thing is that it is scheduled to run every 2 weeks for a few minutes. We have experienced this ‘run’ and it is very comforting to know we have a great solution in case of an outage. In addition, the noise level was outstanding!
