    I have used APC products in the past and have found them very reliable. They provide enough run time to finish what you are working on and then shut down your system (computer). I downsized from a larger model and found the 450 sufficient to meet my needs.

    Works flawlessly, and was priced well. As long as you don't need to power a small office, this should suffice. Good for my modem (alarm system) and allows me enough time to save and turn off my computer.

    I've had many APC units and they all work very well. You do need to replace the battery about every 3-5 years though, but the cost of the battery should be cheaper than a new unit, and you can recycle the old battery at BB. Recommend this for any computer where a power outage or brown out can wipe out your "A" paper for school.

    Excellent Power Backup for CRITICAL Devices

    This product is an excellent unit to provide the necessary power backup needed for critical devices. It will keep them up through short duration power company provided outages, and gives me plenty of time to gracefully shut down systems and devices to avoid the kinds of problems an abrupt power outage can create.
