Great for backing up your modem or computer. Be sure to take out the battery and remove the protective sticker then reinstall the battery in the battery compartment.

My neighborhood was apparently havign some power issues and occassionaly at like noon my power would flicker and go off and come right back on but got annoying for my tv and PS4 while on surge protection still had to power back on and go through the PS4 defrag or whatever. Bought this and now it hasnt happened I have heard the power go off but this is fast enough that the tv and PS4 and other electronics never notice. Just have to deal with the annoying loud buzzer sound when the power goes off.

The APC works as described and APC is one of the best in the business - so do not predict any problems. Was a little confusing on the setup (how to make sure the battery was correctly setup and such) but great product and Best Buy did a good job getting it to me.

Made that mistake twice and made the switch to apc. BOTH my cyber powers died after a power outage and because I couldn't find the receipt cyber power stated there's nothing they could do. (Both within 3 year warranty).

Great product for the price. So far, works as intended. It's a battery back up and a surge protector all in one.

I have had one of these on my main computer for a while now. So happy with it I finally bought more for all the PCs in my house. I have my router and modem on one so that if the power goes out, I keep my PC, and my internet going! Protects against brown-outs (like we had last night!) and gives me time to shut down PCs properly if the power goes out completely. With the cost of electronic equipment nowadays, these are a must. Great quality. Only brand I'll buy.

This is a great little backup power supply for those occasional power outages. I have a Xbox One, 4 port switch and 24 inch TV attached to this UPS. The APC brand seems to have better ac noise filtering and Ethernet surge protection which is a huge plus. For about $40, on sale, it's well worth the price for that bit of protection. I also have one on my satellite system and it works great for occasional power glitches if you are recording an event or movie.

I just lost two HDDs because of the rampant power outages we've had recently. Installed this into the mix...allowed me graceful shutdown time to prevent more damage in the following two power outages!

Everything I wanted and more best describes my APC Network backup. It has met or exceeded all that I have used it for and shows no signs of letting me down. Excellent product, simple setup and operation.

I've been considering purchasing a UPS for quite some time. When I had a hard time restarting my NEW computer after a brief power outage I decided it was time. This is perfect for my needs. In fact, there was a power bump in my neighborhood the other day, and my computers never lost power. Perfect!

These UPS's have saved me more than once. Not sure what is up at my house but I'm so glad I have these APC units. I have 4 running in my office and they are great. Have the battery backup so I have time to shut down my computers is great. The only reason I bought this one is that my oldest one failed. I could just have purchased a replacement battery but needed it RIGHT AWAY. The price is great, so in order to save time I just bought a new one.

It only took one power failure to convince me I needed a UPS for my pc and monitor. Now if the power does go out I am able to save and files I'm updating and shut down the pc gracefully.
