    I was having some spikes in electricity supply at the house, and because of that my new router's firmware was getting corrupted. So I decided to buy UPS and finally chose this one. Now I have my wireless router, broadband modem, DVR, blue ray player and everything else is connected to it. It provides very good security against sparks.

    This backup battery was used to replace one that failed on a network. Kept our network up for a solid 15-20 minutes under half load.

    Easy to install and use. Haven't had it long (reason for 4 instead of 5 stars) but it seems to work fine. Nice and quiet, our old one got very noisy.

    I purchased this to run my DVR and TV (42" LCD flat screen approx 5 years old) as my neighborhood often has power flickers. It sustains power and acts as a circuit breaker great. We have had power issues and not only has it stopped a hard short and stopped a breaker trip - when we have lost power it has done it's job. Run time isn't incredibly long - which is fine for us.

    My electricity goes out at least once a month. The APC 450 gives me plenty of time to safely shutdown my video equipment when I lose power.

    As long as you understand what you're getting you know how trusted APC UPS's are for years around the globe. This is being used to power a FiOS ONT, wireless router, and wireless telephone ONLY in the event of a power outage, your runtime will vary depending on what load you put so know that ahead of time! Love this being in stock and able to pick up same day.
