Summary: Works very well. I did find the unit physically unstable when used in the "tower" option -- worried about it falling over, as the supplied plastic feet were inadequate. I converted it to the "rack" option, with much better mechanical stability.
Summary: I recently purchased this backup. It was easy to install. Customer service was excellent. This backup recently saved my computer and monitor when we lost power for a short time and I was able to power down both computer and monitor with no damage done to either.
Summary: Previous model with similar features had outlived its usefulness; so, when calling technical support and after having them step me through the process of testing the internal battery the decision to purchase a replacement was made. The ordering process, the replacement discount program, the delivery of the new unit and the return process for the old unit all went perfectly.
Summary: All of the APC products are absolutely top-of-the-line. I have owned APC UPS's for more than twenty-five years, both professionally and for my home systems. I have never been disappointed. The accompanying software is informative, reliable and easy to use. APC is my first choice and last resort.
