    I use the battery backup side only for cable box, cable modem, and router. Other items (wireless headphones and TV) are connected to the other side (surge protection.)

    I got this for short term power outages. Typically, the outages are few and for less than a couple of hours. This battery backup is perfect to keep my computer and my phone running for those short outages.

    I bought the battery backup in case we have a power failure. The size is small but fits my needs since I don't connect a lot of electronics to it.

    works great to keep your equipment on when power goes out or you have a power surge. Gives you enough time to shut things down if power is going to out for awhile.

    This is a solid Surge Protector with Back-Up-Battery. Usually looked over by novices, but highly recommended by the pros. Helps avoid network issues when there is a power outage and avoid pointless calls to your ISP

    This works very well for me it keeps you from losing your data if you suddenly lose power by giving you time to shut down. It also protects from power surges.

    Performs as expected for a UPS. This one (the 450VA) is a no-frills version - no display, no AVR (which I do think is important depending on what is being protected), and no USB ports except for the one that connects back to the PC for monitoring. It's a good one to catch, especially if you can find it on sale.
