Bests & Worsts Reviews from Amazon

Editing my review. Have owned less than 6 months, twice it has shut itself down, I've come home to alarm sounding and all systems shut down. Amazon's help desk for this item is closed. Original review: Good and long life battery. Went through a power failure and it kept everything up until I could power it down, however the alarm was barely audible from downstairs. It was annoying rather than alarming.
