      Protect your equipment and don't lose your DVR settings.

      Overall: 5 out of 5

      I live on the end of a long block where the power only comes in from one direction, and since they run it through the back yards, any tree branches coming down in wind storms or ice storms knocks out the power to my house. I have a magnavox DVR that unfortunately loses the recording schedules (not the recordings, just their schedules) if it loses power. So, I got this unit. It is sweet. it protected my system a couple of months ago when an ice storm took out the neutral connection in the power feed, causing brownouts and power surges, until after 24 hours, the limb finally took out the power. The power crew came at that point and repaired the feed, so I had power again, and aside from the annoying beep from the ups during all that time, I still had all my DVR schedules, and none of the equipment suffered from the ordeal. Worth every penny.
