Rated 5 out of 5 by from Solid!Have owned this product for about a year now and it has been rock solid. Been through two power outages with it and it has supplied more than enough back up power and kept my devices from any power related issues. Top notch!

Rated 5 out of 5 by from Glad I upgradedI finally broke down and upgraded my UPS. I had a very good UPS from APC, but since I now use Mac OS 10.8.5, I could not make use of the old UPS. The old UPS did not have a usb port. Well, I did buy it new in 2003 and it worked fine with the older Mac OS 9.x. The new one has a usb port and works great so far. All I had to do was unpack it, open the battery cover, plug in the red connector, replace the cover and plug in the power cord and usb connection to my trusty old iMac. Other than possibly needing to replace the battery at some distant time, I am certain I will get a long life from this UPS.

Rated 5 out of 5 by from Work's Great!This UPS came in handy during the electrical upgrade of my house wiring. My PC never went down when power was temporarily shut off and it even warned me when neutral and hot were reversed. Best yet, the unit runs cool. It's just well designed and I have five around the house and another six in my office protecting everything from switches, PCs, secuity and telephone systems.

Rated 5 out of 5 by from BackupsWe use these units throughout our company and they work well. This was a replacement/upgrade for one with a battery that was going bad. We seem to get about 6 years + out of a unit before the batteries start to show signs of needing to be replaced. In our areas they are a necessity as we get power outages and spikes enough that without them there could be some serious damage or loss.

Rated 5 out of 5 by from Dependable and AffordableI've been using APC products for many years. Since I traded in the prior unit for the current model, there haven't been any blackouts or monster power surges but I expect it will eventually save my bacon as its predecessors have.
