Already had a couple of power outages from thunder storms recently and this kept my server running without a hitch! I also like being able to see how much of a load is hooked up to it and how much time it's expected to have with the current load.

Well packed manufacturer packaging. Very clear multi-lingual user manual that is well worth the time reading the few pages in your chosen language. Very clear warning markers attached to UPS. Very difficult to install and use this unit without seeing the warning marker to connect the internal batteries. Silent operation; it does not have any fans on/in it that I can tell. Novel "master slave" outlet pairing. Lose power to the "master" device and the "slave" device turns off immediately. The manual tells me this feature is disabled by default, but read the user manual carefully to fully understand it's operation.

I've read many comments about the design of this unit, but when I needed it today, it worked! I had a lightning strike close to me and the house power died asap. There was no hesitation with this unit. I have used Tripp Lite UPS' for a while and all have worked well.

Didn't have to mess with it to get it up and running. Previous UPSes had to have the battery connected. Not so here. The one brief power blip I have had allowed my computer to keep running.

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 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.
