You buy one of these if you want a quality, powerfull UPS. It is well built, easily controlled from the front panel, which provides plenty of information about the UPS state. In use it is quiet when the line input is OK. Once the line is lost the internal fans etc kick in, but thats what you expect with 2200VA of backup. It is built like a tank and when fully loaded with batteries weighs a ton, so make sure your rack is strong enough to hold it.
