    Our Geek Squad installer recommend this product to protect our investment of a OLED65 television. Our power fluctuations are bad for our receiver and television. This product protects them from the highs and lows. In the 6 weeks since we purchased it the alarm has sounded 4 or 5 times indicating a power surge or drop. No problem for tv or anything else. We are very happy that we purchased this product.

    I have had this unit for about a month now. Got this one because my old one was not supplying power to the battery back up outlets. Like that it has a voltage regulator. My old one did not support the software since it was out of date. Now I can monitor the status of the unit on my computer. It also tells me when there is a power problem. Have not had any problems with this unit. Would buy again.

    Recently my UPS battery died out. I noticed this because my computer would reset every time I ran the laser printer. The UPS would click but not switch over to battery power. So, I replaced the old one with this model. Solved my issues, as I would hear the click after printing and my computer stays on. Plenty of space between outlets for your oversized AC adapters.
