    This is a good purchase if you need to mitigate minor brownouts or spikes in power to your critical components. The specs say that this has auto shutdown software but the one I received did not have that capability and I believe based on CyberPower's website the next step up from this does.

    I've used CyberPower for many years and have had very good success with them. This one was a replacement and priced such that it didn't make sense to try and replace the battery. Good products...........I own several.
