I have not had my Tripp-Lite UPS very long, but so far I like it. I use it as protection for my computer and other equipment. We get frequent blackouts, brownouts etc here. It seems like a sturdy quality product so far. I also use the power alert console along with it. It works very well, it is a java program so a little differant than a windows program, in the end probably makes it better though. The power alert console is great but manual could be a bit more detailed. A person without a lot of computer experience might have some difficulties with it.
