    I used it to back up power for an internet modem and a wireless router. It does its fine. However, after a few years being plugged, it does not maintain an acceptable duration during power outages. It is somewhat disappointing that it doesn't last long before the backup battery needs to be replaced.

    It seems to be a well made, sturdy unit. Be sure to read the description as some outlets are surge protected only not battery backup. Cannot comment on its effectiveness as we have not experienced a power outage yet.
