    I'm on the same circuit as my next-door neighbor and we have overloaded the breaker a few times so the battery is nice to have I can turn off my PC when we lose power.

    The only reason I did not give a 5 star was I do not know how long it will be before I have to replace it again. I know it will need replaced, but will it last as advertised?

    Our surge protector/battery back up gave out, so we needed to buy a new one. We'd bought our last one at Best Buy, and were satisfied with it. It had lasted a long time, and had worked well. This one is the same or similar to the one we had before. We really like the fact the outlets face out, so there's no problem with large plugs blocking the next outlet. Works great, and we feel good that we are protected, and have the back up we need.
