Excerpt: I think we just had a small test on whether or not this works. The power flickered and a message came up on the screen that AC power was restored. We had purchased the same model previously but it seemed to slow down the computer. Not being an IT person I assumed it was the backup. This one seems to be working as it should. It does not come with a software disc to be sure to get online and download it.We have not had a good test yet and hopefully we won't.
Excerpt: The unit works fine, but I can only give it four stars. The reason is if you could replace the battery at a reasonable cost to extend the useful life of the unit and thereby reducing the electronic waste would be very good. Unfortunately the cost of the replacement battery is almost the same as buying an entire new unit. Add the cost of shipping and you are better off with buying a new APC Back-UPS.
Summary: Works as advertised. I agree with other reviews the battery has a short life. I have a desktop, monitor, and printer plugged in and the battery lasted less than 15 minutes. However, during short brownouts, it works great.
Summary: This unit replaced the power strip that was used to power the tv, dvr and surrround sound. It installs just as the power strip was, although it is quite a bit larger and heavier. After allowing it to charge overnight, I tested it by unplugging it from the wall to create a "power failure". With everything powered on, it worked flawlessly and gave a series of loud beeps to let you know that there was a power failure.
