    This backup does exactly as it should. I have key things plugged into the battery part and not as important plugged into the surge side. My area gets lots of power surges and this is doing a great job protecting against those hurting my equipment.

    Protect Your Computer From Power Outage

    I had a power outage the other day and my computer went off and on several times. A quick off-on of the power is a very sure way to do damage to any appliance. I use QuickBooks and it caused a malfunction in the program. I had a surge protector on the computer but it doesn't protect from a quick off-on of the electricity. So I bought a battery backup so the next time there is a power failure with a quick off-on of the electricity, my battery backup will keep the computer from going off and back on quickly causing more potential damage.

    Repeat Purchase

    This is the third APC surge/backup unit I have purchased. One of the three was a replacement when my first unit's battery died. While I believe that battery life should have been longer, I am overall pleased with the performance for price with this brand. I gave this purchase only a "good" because I have yet to see how long and how well it will do its job.

    Excellent Protection

    This is my second purchase of this item. The first protects my cable modem, printer, router and other network accessories. Seven years and I have just replaced the battery. This purchase will protect my entertainment center. I live out in the country where power is sometimes sketchy, and I'm certain these have prevented me from the need to replace equipment due to the numerous brown-outs that we suffer through.

    Staying Power for your Network

    I purchased this strictly for my modem and router. I have a 1500 APC UPS for my computer but it didn't make sense not to have something for the network. Just in the past month, I have had two hits on my power which I would have had to wait for everything to come back up. I also get brownouts and this protects them from damage. I had another unit on these but the battery failed after two years. I am a long time user of APC UPS's and I am disappointed in myself in trying to go cheap when this was available at a relative inexpensive solution.

    These are great, we have power blinks many times a week and they always seem to come when you really don't want them, like when downloading updates ! Not a worry anymore. I now have 3 of these and always will, need I say more.
