A very intelligent display panel.

Really like the display

Nice digital display, easy to use this.

But if you realize that this is, in my opinion, nothing more than a few lawnmower batteries packed tightly inside a metal case, with some supporting electronics and a fancy display, you'll see that you're only buying a few minutes of up-time upon power failure, and reliability of these devices has proven to me to be equal less than that of the desktop PCs we use in these locations
