This is the second Ultra UPS 1000VA AVR Backup System I've purchased. They work Great with the occasional power outages we've experienced recently.These units are highly recommended for your computer network - they keep things going long enough for you to shut down the computer properly.
First one was dead on arrival but quicklly replaced and second one is working great.
I ordered the Ultra as a replacement. The power went out several times due to flooding and downed power lines and eventually caused my Tripplite UPS to stop functioning. I live in Florida (lightning capital of the US) and recently tropical storm Fay dropped a lot of rain on us. A small price to pay since it was protecting my plasma tv and cable box. It arrived on time and works reliably.
With write caching enabled a power outage can mean a complete loss of all data not cached. I purchased this product for my father to deal with outages/brownouts. Anyone running a raid configuration will know losing power leads to annoying hour long reverfiys of the drives data. This device has saved many headaches on multiple ocassions.
This type of unit is superior at stopping those annoying brown outs that don't really take your power down but they make the power "blink" just long enough to force your computer(s) to reboot. If the power completely goes out it also gives you enough time to save documents and turn off your computer but don't expect to fire this thing up during a hurricane and play games for hours. I'd say it lasts 5-20 minutes under typical loads.
