    I bought this for the price and was hoping it would do what I needed. I get power spikes where the power turns off just for about a second and then back on. Before I was losing stuff and having to start over if it wasn't a MS product with the auto save. Now if it happens my two pcs just keep right on going.

    Just what I needed for my internet back up power supply. Hopefully I won't need it, but I feel better knowing it is in place. A good price as well, I think.
