    Works good, we average a 2-year life on the battery, so we replace at 2 years unless failure occurs prior.

    I live in FL. which is the lighting capital of the world. We need protection for our electronic items and this will protect it. I will be working from home and this is necessary to protect my investments because my employer isn't paying for it. Don't wait until it's too late. Get yourself one. Make sure it has enough power for your electronics. Best Buy will help you with that.

    Battery Backup

    This cyber power battery back up is terrific. With recent blackouts of power, this type of back up is essential to have. The electric company, PG&E keeps having black outs to prevent winds blowing power lines into very dry trees and setting off sparks and thus starting added fires, it is necessary for power shut offs periodically. This battery back up is wonderful.

    This power box is worth to get if you are PC gaming and/or other things that uses electricity. This back up battery really saves your PC and other electronical things from dying or frying up whenever there is a storm.
