    This product takes up a small footprint and still provides enough outlets for most setups.

    After consulting with both the Geek Squad and sales personnel, we decided this was the right unit for protecting our computers. It was a good decision and was based on the Best Buy Technical personel who are quite experienced.

    Had a power outage during storms on 6/12/2016. Power off and on 5 times but computer and monitor never blinked, stayed on and allowed me to shut down normally.Better than any surge protector as the battery keep you going. Worth the small extra charge to have the back up battery versus running the best surge protectors alone.

    I purchased this unit as a replacement for an identical unit that was purchased seven years ago. It is used as a battery backup on some medical equipment and I can only hope that it works as well as its predecessor.

    I have been using this UPS model for years. It has always been reliable and the battery lasts for years. I especially like it because it is lighter weight than similar models of other brands, so it's easier to move around.

    Purchased the unit to support a computer, router and monitor. Already had a power outage, and the unit worked just as advertised. It allowed me to finish what I was working on then power down the computer properly.

    Cyperpower UPS's tend to provide good battery backup and surge protection as good as the big names but at a much better price. I use Cyberpower UPS''s in my business and have for many years and have never been disappointed.

    I bought this UPS after an older unit (5 years+) failed. I got an excellent deal by price matching with Costco. The UPS has been working for several weeks now, but has not yet had to switch over to battery mode.

    I wanted something to protect my new laptop without breaking the bank. I plugged it in and let it charge up and then plugged in the laptop. It worked well when I pulled the plug and the laptop didn't miss a beat.

    This type of device is binary - it either works or it doesn’t. Well, this one works just as it is supposed to. Powering iMac and printer and providing power surge and power outage protection. Worth the slightly higher price compared to a simple power strip with supposed power surge protection.

    This surge protector and battery has worked well. I wanted to protect my computer with something that would also give me time to save my work should the power go out unexpectedly. This device has worked perfectly.

    Purchased this particular item as a replacement for an identical 7 year old version. Was very happy with both my first purchase and my recent purchase. This device is perfect for the non power computer user.

    Bought to replace a failed one. Works just great as always. Never had any issues with CyberPower battery back-ups. Slowly replacing my APC's with these because the batteries seem to hold out longer on these.
