    It replaced an equivalent item of the same company, but it lacked one connection that the old one had.. For some reason it makes a sound when I use my printer, which is connected to it.

    Provides good back up time for my wireless router. Have a second unit that backs up my Modem and DHCP firewall. Both perform well and fit nicely in the small space that is allocated for them.

    I purchase these power supplies for my business, and have never been dis-satisfied with the power supply. At 15-20% less than comparable brands, this is an excellent value.

    I was looking for an UPS for my home networking setup and I found this one. Good time for safely shutting down my NAS in the event of a power outage, solid construction, overall very reliable.

    where I live we have a lot of storms. It is essential to have a backup power and battery source. This is a small device, perfect for my needs. I't hooked up to an XBOX and TV.

    This is my protection vs. brownouts. Should have bought one a long time ago. The battery & extra time to shut down is a bonus, and the price was excellent as well.

    It's large, quiet, and protects my computer from getting zapped. I also like that it has a built in battery so I can finish up what I'm doing when the power goes out.

    I wasn't very impressed with this product, I took for ever on the initial charge, if i have one of my computers plugged into it, works fine. When I plugged in more than one computer, it will not keep them on, found out the hard way during a recent storm

    As surge protectors go, you must expect that they should work. This one is worth the cost. It's a bit heavy in weight, which can be good for stability on a wobbly surface.

    The CyberPower is dedicated to my Router and Ooma. Appears to be well made and does work perfectly when normal power is lost and should provide decent surge protection.

    It's a UPS. It does what it does. It's solid. And it's cheaper than APC. Haven't had it long enough to see how battery life is but it does what it does for less. We will see how it evolves.
