Rated 4 out of 5 by 2 reviewers.
Rated 4 out of 5 by Great features, easy to install, easy to operate. Installation was quick and easy. More than enough power to run all of our essential circuits. Starts for its weekly exercise routine right on schedule every week, even when it's 2 degrees below zero. We haven't had to put it to a practical test yet, but that will only be a matter of time. Meanwhile we sleep better at night... February 11, 2014
