    I purchased this higher capacity model because I needed to add a weather station display to my battery back-up system. I have been using an APC lower VA model for my computer and monitor for nearly nine years with no problems at all. Only replaced the battery once during that time. This new APC unit has more power and additional outlets for my expanded system. Absolute cinch to set up. APC makes a quality product.

    I am currently using this with my entertainment center setup since I have an Xbox one x and a ps3 that I wouldn’t want to lose power when they were performing an update for example. I love that this has 9 outlets and is just enough for my setup. I moved an APC battery backup box with 6 outlets to my basement entertainment setup but that is also still working perfectly. The six outlet version has saved my setup several times when we have had short power interruptions.

    Installed this in conjunction with my NAS. Works flawlessly and can even signal to my NAS that it needs to shutdown if it has been on battery backup for too long. I have my NAS, my router and my modem plugged into it and it easily handles 30 minute power outages. Gives me plenty of time to save my information from my laptop to the NAS or send an email to the utility company to tell them my power is out

    Since it's brand new I'm really reviewing the last one I purchased YEARS AGO AT BEST BUY. Through all the lightning storms and loss of power both momentary and long term, I've been able to continue delicate maneuvers in Photoshop and finish large photographic printing sessions without a single blip. this new one is an update of the earlier model I had and presume it will serve me just as well and the price was the sweetner - - -

    My husband lives in a hospital bed on an air mattress and our house is at the end of a power line. Occasionally we have power hiccups. Our last outage lasted 2.5 hours. This unit is a time upgrade.

    Of course until you lose power you can’t really rate a product like this, but it has the right mix of protected and battery backed outlets BUT the outlets could be more separated and/or alternated to enable some of those awkward plugs to better fit.

    I had bought one a while ago just to give it a test to protecting multiple electronics in a power outage/surge. I can say that it did amazing keeping everything on so I bought another one and plan on making sure that all my devices are protected and backed up. Best Back-UPS ever. One downside was installing the battery. I had to put the cover on multiple times because it wasn’t sitting right.

    When my very old APC finally gave up, there is nothing better than getting a new one, at a good price, in the time it takes to order it online and drive to the store. The order was ready, as usual. If you worry that they might give you an "old" box, the box was clean, no dents nor dings and made very close to the time I bought it. APC generally makes good products. I intend on this working for 5 years or so like the last one.

    So far this has been sufficient for our needs. We had one of the same brand and power which functioned properly during a storm and power surge, It protected our electronics. The company replaced it with this one as it took the "hit" and not our electronics. We will never be without good surge protector and this one has our seal of approval.

    I purchased this to go with an Echo Dot I was using for an alarm clock. It was a bit overkill, but I was worried if the power went out, I'd miss my alarm. Set up was easy, and it would have powered the Dot for quite some time before running out of juice. In the end, I ended up returning the Dot, so this went back too. I'm starting to wish I would have kept it though to run our modem and route incase of a power outage. Might buy it again.

    I bought this as an upgrade to an APC 450 va battery backup for my home theater set up. I have an XBox one and ps3 that have hard drives and I didn’t want power interruptions during system updates etc. The 450 still works great and I just moved that to a different room / tv setup. It’s nice having three extra plugs for a total of 9 vs the 6 the 450va has. APC products have been reliable for me.
