    Love having more wide-spaced outlets on this unit. We had a power disruption due to bad weather a few days ago and this kept the equipment running long enough to let me shut it down correctly.

    We were moving to the Caribbean and needed a backup power system that would effective where we planned to live. This system does very well in daily use and for the rare short times we may lose power. It is actually useful for smoothing out the power going to the electronic devices!

    Really does the trick when the power goes out

    I installed this backup unit in my home office after getting tired of losing work on my computer when the power goes out (which seems to happen somewhat regularly, unfortunately). I have the computer, monitor and modem/router plugged into the unit, and now when the power goes out, it gives me about 20 minutes of operation. It's been great to have time to shut down cleanly. I also like that I can turn off the alarm, because I really don't need it waking me up when the power goes off in the middle of the night. My only recommendation for a different unit would be depending on how long you want backup to go. There are similar units with much more battery capacity. For my needs, this one works fine.

    Affordable price for a battery backup. Seems to be working great so far! Always glad to have Best Buy close by to pick up a need product quickly, since we have a lot of power surges at my house.

    Hooked my cable system up to this so I would not have to reboot UVerse everytime it goes away. Had a power outage a couple of days ago and it kept working beyond the stated time.

    Good battery backup system. No issues with the installation out of the box. Is being used for my modem, router, LED TV and has already kept those devices going across several short power drops.

    Works great for the office for the power surges/cliches that usually restart your computer. With this I don't have to worry about my computer loosing unsaved data when the power cliches.

    We have had a problem in our area with power flickering every few days. This would constantly jack up my router and we would lose internet. Now my router never loses power. Problem solved!

    I have used this product for many years and needed to upgrade to a larger model. When the power cuts off the Cyberpower unit never lets the computer cut off. It has a very fast cycle rate.

    We have this connected to a single PC in an office. It provides about 30 minutes of uptime in case of a power outage. It was easy to install, sufficient for a single desktop PC and monitor.

    Decent power strip for the price with battery back-up. Owned this brand in the past and it just wore out. smaller than the original version which I liked to see the smaller profile.

    I use this for work to make sure that the data on my computer won't get lost in the event of a power outage. It won't run my computer for a long outage, but long enough to get to a stopping point in what I'm working on and shutting down without losing anything important.
