APC is the only brand of backup I would buy. This thing is great for a surge or outage. Gives you time to shutdown if you need to.

It functions like the description. This is my second one, the first is working fine and still being used with the original battery.

This product was worth the investment. I seem to get more than my share of very temporary outages when storms roll through and this keeps my internet and WIFI up. Thinking about buying another to cover my primary TV and cable box.

Since activating this device we've had 3 or 4 surges and one hour of power failure and it has continued to function as designed.

We chose this surge protector based on the clerk's recommendation after answering some of our questions. It works as expected.

Have owned an earlier model and was well satisfied with the protection.
This newer model doesn't have the program to shut the computer down. While this is minor, compared to the protection it provides, it still was a nice feature.

My only gripe is that I wish that there was an option to turn off the alarm when the power goes out: don't need it

UPS works as expected. Replaced 5 year old unit after battery died. Easier and cheaper to replace entire unit then look for battery replacement only.
