    This is an essential product if I wish to use a computer. Although we do not have a lot of outages, I know from past experience that a spike in voltage can damage electronic equipment. This is the same as experience.

    I needed a quick replacement and this one was available quickly, boy I was glad it was. This unit has the best stats than any of it's competitors of it's size. I plan to buy Cyberpower when I need any future replacements.

    Gets hot easily. Consumes a lot of amperage when one has only 15 to use.

    You never know if your power is going to spike, dip, or just go out. These are a must have for electronics, and they are great for aquariums too, if your pump/filter unit looses prime after a power outage.

    This is a really great UPS back up and I have had one before. It was affordable and I knew the quality would work and there would be enough power to shut down my equipment before I lost valuable information.

    I had a lightning strike take out my Apple computer and Smart HD TV because I thought a surge protector would keep my equipment safe. I was sadly mistaken. I went to Best Buy and was shown the product that would safeguard my electronics.
