    Real easy set up and very affordable option with a battery backup at a cost equal to just a surge protector.

    I like the compact size and the ability to turn off the alarm. Had I realized the plugs wouldn’t accommodate large plugs side by side I might have opted for the bigger unit that does. Otherwise just fine.

    This is a solid choice for the money. It provides adequate protection against power ebbs and surges. I would give it a 5th star if it provided for auto shut downs but really you have to pay much more for those features.
