    Awesome backup for the price

    At first I thought it didn't work but silly me plugged my Mac into the wrong side LOL. 4 outlets are for surge protection only and other 4 go to the battery back up. I use an iMac and it works perfect for it. The battery won't last forever but I under stand it is just a backup and not a generator. The price is awesome as I paid several hundred dollars for an APC battery back in the 90's. I will keep buying APC as long as they keep their quality up.

    APC Back Up

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Out here in the country we get power surges all the time. After a close friend lost several appliances due to a power surge and no reimbursement was a wake up call to me. So I took matter into my own hands and purchased this APC back up unit. Since then, when a power surge happens, I hear a click from my unit and no power loss occurs. I feel so safe now knowing I have made a great decision in purchasing this great piece of equipment. "Better safe than sorry" as they say.

    Awesome Product

    Had to get a new computer a couple years ago and when I bought that I got this too. I was so glad to get it cause the power where I live would always have slight surges constantly that would shut off the computer. Have had this product for 2 years and has saved my computer hundreds of times from power surges and outages. Only downfall I think is that whenever the battery kicks in theres a loud beep which can get pretty annoying if theres a surge in the middle of the night. Other than that everything works fine and have had no problems.

    This does wonders when your power goes out and you still want to have some ability to go online or keep some vital systems alive until the power gets back. Now, its battery reserve is limited, especially whne you have many items hooked up to the battery, but still.. it's a great backup solution to have. Plus, it's a surge protector too... can't go wrong with that also :)

    Basic UPS for nonsensitive electronics

    Installed it to keep some networking equipment and other miscellaneous electronics up for a minute or two when the power flickers during thunderstorms. Appears to be doing the job without difficulty.

    Limited Ethernet Throuput

    Posted .
    This reviewer received promo considerations or sweepstakes entry for writing a review.

    Since this is labeled as a network UPS and comes with cat5e cables I'd expect it to be able to handle modern gigabit networks. Unfortunately, that is no the case. When running through the ethernet surge protection on this device my network peaked at ~80mbit whereas without I peak at ~890mbit (server has a 300ft wire run). Only reason it still get's three starts is that the battery backup does work to keep my network from resetting everytime our power blinks (which is numerous times per week). Hopefully protecting the input voltage is enough to save my equipment next time but i suspect I'll be replacing switches again next lightning storm.

    Needed a battery back up for our editing system. Have one on another system and it works perfectly, so we bought another one.

    If you want it safe, get a UPS from APC

    This reviewer received promo considerations or sweepstakes entry for writing a review.

    There are other cheaper brands out there but these guys are the best and its worth the extra money. Their APC warranty is great too and if the device fails, they WILL pay for all items connected to it that were damaged. I ONCE switched to the other brand and immediately noticed how much lighter it was which is a sign of inferior battery design and cheaper electronic components internally. APC or nothing!
