    I purchased this item in lieu of getting an additional power surge protector for my computer equipment upon the recommendation of the sales associate at Best Buy. This price was reasonable and I feel that now I have extra protection should I experience a power outage. This will give me the opportunity to address the issue rather than just waiting until the power is back on.

    I am a huge APC fan! If you buy the latest technology, you need to protect it with a powerhouse like this one! APC stands behind their products too. When there was an issue within warranty period, they had a new one to me within days. Will always buy APCs for my surge protector needs.

    Had a blackout, I have this powering my network devices and a NAS storage device. Has it connected via USB to my Netgear ReadyNAS. I was out and got an email from the ReadyNas that the UPS was on battery power. A short time later I got another email that the power was restored and the UPS was back on line power. Pretty cool.
