    I ordered a lower wattage unit for the cost, but because I am using more efficient equipment I STILL have about 20 minutes of run time. Very happy with the quality and to service from Best Buy!!

    Had three power failures in the last two weeks. Computer remained powered and I was able to logically shut down. Windows 7 pro recognized the UPS and loaded software to shut down the PC if not home when powered lost.

    I had the same Battery Back-Up System for almost 5 years and it died, so I had to replace it. Does the job, the battery part died but was told by friends it was cheaper to buy a new one. Paid 64.99 then went on sale about two weeks later for 49.99 and BestBuy made good on their price guarantee.

    I have a lot of short power losses where I live and this works great to keep my computer on. I wouldn't be without it. Eventually the battery has to be replaced, but that is an easy buy and easy to install too.

    I lost 2 computers to lightning strikes. Bought my first CyberPower 12 yrs ago. It's been through several lightning strikes and power failures, and has kept my computer safe. Time for a new one.

    This backup is the best for the price!! You can spend a lot more if you want, but in the end, you can expect to get 3 to 4 years out of this one and the more you pay, doesn't get you any longer life!!

    This is a great product to ensure shutdowns due to power failures, allowing the saving of files prior to the battery discharge, The included surge protector for devices and phones is also very helpful.
