    Has saved my tv and Xbox the pain of restarting when power has gone out. Very much worth it! Might get another one to power my POE cameras.

    Great product. I buy them frequently for my work and they haven't let me down yet. Has plenty of space to plug in multiple items. I like how some of the outlets dont use the battery so when power is lost only the necessary things are draining the battery.

    Great for the slow to re-boot cable box

    We have always had issues with periodic brief loss of power in our building. They are so brief, that they only affect the cable box. However, it takes the cable box forever and a day to reboot, so I bought one of these for the cable box and one for the aquarium filter, because sometimes it won't restart by itself after a brief outage.
