Pros: great price for the VA it is rated to deliver. Eco mode option or dual conversion possible, Eco mode switches fast enough for my equipment so a nice plus. LEDs indicate status (mains AC, battery, ECO mode, bypass, etc) and are always on, so it's easy to see.

Cons: Assembly/build quality issues. Battery pack is 4x12V sealed lead acid batteries, but the wiring connecting them used crimp connectors that simply fell off. Every connector felt loose, it took a couple hours of my time to fix. The front bezel feels chincy, and the LCD text display is both crooked and refreshes too slowly to display fast changing input, e.g. the measured load. The cooling fan cycles between low/high speeds very regularly (every 6 seconds or so?). I can hear it from where I usually sit, can be quite distracting. I believe it cycles due to my load cycling so this may not be an issue for other users. The menus and buttons would be very difficult to navigate without the manual. Keep it around!
