Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    This unit fits nicely behind a bookcase or cabinet. When the lights go out it makes a loud BEEP, that is annoying after a little while.

    A good, basic battery back up system.

    What this isn't: a $200 UPS system. What it is: a very reasonable UPS for a few devices. This is great for a single desktop, or perhaps your router & wifi and a few things. The charging USB ports are a nice add on. It has a nice flat plug, curved to one side so it will fit behind furniture well. So unless you need gobs of power from your UPS system (heavy pulling devices), this should be all you need.
