Customers are saying

Users appreciate its ease of use, excellent value, space-saving design, and adequate surge protection with plenty of outlets. While some find the plug spacing a bit close and the unit somewhat heavy, the noise level is generally acceptable. Overall, the positive aspects of the product appear to outweigh the minor drawbacks.

    Works well. This unit is very compact, but still provides ample space for plug in transformers. Installation went smoothly without any issues.

    Fantastic UPS

    Love this UPS. It is practically silent (unlike some other brands) and the outlets are well spaced to allow compatibility with most plugs without blocking outlets. I strongly recommend doing your research in advance of purchasing to understand how long any UPS will support your connected devices on battery backup. Misunderstanding UPS abilities is the most common mistake made by purchasers of UPS systems.
