Does it's job. Works with my FreeNAS system to gracefully power down when the power goes out. Smaller than some of the older UPS systems I've owned. Very nice LCD display with measurements such as voltage, run time, and power output (see other thoughts). LCD can be activated for a few seconds at a time by pressing a button, or locked on so it stays on all the time.

-Seems to last. -I can run my computer (with my Yeti and monitor) off of it for about 30 minutes, in the event of a blackout. More than I imagined, I just wanted something to last 5 minutes so that I can safely shut my computer down. -Easy to understand what everything means after reading the manual, such as if its green, blinking yellow, and other stuff.

Ok, to get this out of the way--ONE button does everything. Not the most convenient thing for consumers to do but simplifies things for the maker of the product except when people call them and go "blah blah, how do I do this or dat?" The instructions come with it on how to set settings though. Voltage trip range could be set to sensitive, normal, or high. I left it on normal, which is preset, and it tripped once within a week--I heard a click from the unit, which means it activated. Also, audio alarm could be disabled (or couple other options as to when it would activate), all of which also is set by one button.. meh. You have to hold button for so long, blah, do so long of a press blah, blah blah... meh. Green power LED is very nice looking but too bright for bedrooms, so I had to put a sticky note paper over it and paint that area with a black permanent marker (in reverse order) to keep that light from shining brightly in the room. Overall: it is a very nice polished looking product for a reasonable price.

I've had this about 2 weeks. This replaced a Cyberpower UPS that died. Not much to say about a UPS. I bought this to place behind my TV and console. I was tired of loosing power for a second and having to wait an eternity for the cable DVR to boot back-up. Living in the lightning capital of the USA we see a great deal of power outages. The size and design of this UPS works great for my application. I have my TV, WiFi Router, DVR and Google TV player on this UPS with no problems. Hopefully this will provide the back-up I need for short outages and brown-outs.

I've owned this UPS for several trouble free years and am completely satisfied with it's performance. I bought it when it was first coming to dealers. Newegg didn't even have it listed yet so I got it from another place. With computer (7 fans and single GPU), 42 inch TV, printer, modem, and router, I have 12 minutes of power before it's ready to shut things down. Setup is fairly easy with the software and I prefer to use the on-screen interface rather than the pendant. This thing is super quiet when you are not drawing power from it. I've called technical support before and was always treated with respect, having my questions answered.

I like the fact that I can plug my high end computer into the APC SMC1500C along with my monitor, printer and other components into it and still not having to max out the total power consumption. I like the way the screen is so I can read what I need to see the UPS is working properly.
