    I had a power outage and the settings on the DVR and TV were intact saving me the trouble of having to reprogram. On a stereo that wasn't on a backup, I lost all my set radio stations! Needless to say, I'll be getting another one of these Back-up systems. The price is right.

    I've had good success with Cyber Power UPS battery back-ups in the past and they will continue to receive my business. They last a long time and I appreciate that they have more outlets and have a nice layout to accommodate the many different styles and sizes of plugs.

    Great for a game console. It doesn't have a usb port for software and a game console can't use one.

    When our desktop started to reboot or the monitor screen went black whenever we tried to print from the laser printer, even though it's a wireless printer, we finally determined that our 4-year-old UPS was dying. By replacing it with this new one, everything worked fine with no hiccups at all.

    I have several CyberPower UPS and needed a replacement so I purchased this one. It is the right size for what I needed. It can hold larger plugs. But it really needs at least one plug holder at the opposite angle since the plug for my switch is long and therefore covers 2 plugs.

    I am loyal to the CyberPower backup batteries. Working from home means that I have to make sure I never lose any of my work during a power outage. These last for years and provide a peace of mind that I'm covered in the event of a power outage.
