    This product was used after the recent Hurricane in S FL. I plugged my computer, credit card machine, phone and fax to it; due to power outages in the area. When power briefly went out during short outages business was not interrupted;)

    I needed to replace a dead APC backup and this fit the bill. Only been using 1 month, but seems to work. I killed the power to the unit and it kept things running. I you have a powerful computer that draws a lot a power, obviously get something more robust to give you more time.

    Great battery backup for the money. Easy to use, just enough outlets for my devices and provided room for larger power supply heads.

    I bought this specifically to provide backup power to my router and home security DVR. During a power outage, pretty frequent here in Florida, the router and DVR wouldn't sync after an outage with the same IP address. This handles both with ease.

    Exactly what I needed for my home office

    These backups were perfect for my home office. Install took seconds and reading the instruction manual lets you know that they need to be plugged in and the power button held for several seconds to turn on initially. Due to my location next to an active rock quarry I have flickers or brief power outages (lasting mere seconds) several times a year but with these backups I never see a drop in performance or lose precious work. I have my beefy gaming PC, my router and modem and even my Xbox One all on these backups and they work great,

    This is my second purchased 650VA back up system. Our power does not go out very often but the lights do flicker quite often when the winds blows hard, probably five times a year. This unit has always worked flawlessly and I have never suffered any kind of equipment failure either from fluctuating power levels or actual losses of power.

    Battery backup and surge protector combined for power failure provides enough to finish what you are working on and shut down correctly.

    I purchased this Battery Back-Up for my second computer. I already have one from Best Buy for my other computer, have owned it two years with no problem. Both worked for a recent power outage in my area. I recommend this product.

    I use it for my PS4 and 27 inch monitor. In our area when a storm is coming sometimes the power will randomly go out, sometimes just a few sec, sometimes it can be hours. This UPS makes sure the PS4 doesn't get force shut down. If power goes out for few sec, I can keep playing; if power goes out for a long time, the battery provides enough time for you to quit the game and properly shut down. Pretty sure you can plug in 2 consoles and a monitor at the same time, but for a high end PC it's not enough though.

    Purchased a couple weeks ago. We had a power blip a few days ago. The unit provided power to our desktop computer and monitors without missing a beat and I was able to continue working without interuption.

    I have bought many of these over the years at different ratings. Have had only one die on me due to a horrible power surge. While it did not survive all of my equipment attached to it did. Would recommend.

    We use these UPS models for our PCs at work and they work great. 650VA should be sufficient for most mid-to-high range PCs. If you're a gamer, however, I'd go for something closer to 1000VA.

    This is good for short term power back up. I mainly purchased for a protector incase of power surge.
