Rated 4.7 out of 5 by 3 reviewers.
Rated 5.0 out of 5.0 by GREAT UNIT! My wife and I purchased this unit for our home in the mountains in San Bernardino, CA. We have had the unit since January, 2011. I have MS and I am disabled, we have chair lifts in our home and God forbid I need to be on a ventilator it would save me. The unit self test for 20 minutes every Saturday. It is quiet and really is white noise. We have had several power outages in the past year the longest lasting 5 hours in the middle of February in a huge, cold, snow storm. The generator kicked on right away and ran our whole house with no problems. It runs on natural gas so with natural gas you only get 18000 W but more then enough to run everything in our house and then sum. If you have the means and the need I highly recommend this unit!!
