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.

    I needed something thin to go under a piece of furniture. This fit perfectly and during a recent power outage it kept my router and Arlo base station going for 45 minutes. This helped me stay online while teaching. I have a total of 3 different backup batteries and for summers in Florida they are essential.

    Compared to other brands of similar rating, this had as much power, as many outlets (or more), and for a good bit less money.

    Plugged this BBU in on Monday and had a power cut on Wednesday. This ran our complete video security system (8 cameras and system box) for 35 minutes before it ran out. Plenty of time to record the crooks in the act. Would recommend. Prices are getting crazy though.

    There is nothing not to like about this UPS. It fits perfectly in my network rack cabinet to keep my PoE cameras powered during power outages. It is slim enough to take minimum space yet provides enough power to keep the PoE devices going long enough to safely shutdown or ride out the short power outages.

    This battery was the perfect size and shape to put behind furniture (and out of sight) so the furniture would not stick out too far. So far, there have been no problems.

    This is a perfect battery/surge backup for any computer or AV setup in your home. Multiple inputs for your electronics help keep piece of mind for random power outages. Wish i got a bigger size for longer backup times.

    Needed a good battery back-up. Now understand it has been awhile since I have purchased one of these. I was startled at how inexpensive it was. Very pleased with the product and its price,

    I am a science teacher and have a desperate need for reliable power. This UPS has already paid for itself when, during a lab project, the electricity went out for over 30 minutes and I was able to complete the project for my students without any difficulty. What a great investment!!

    This is a great UPS. We don't have power failures here very often BUT we do have "dropouts" when high winds short out the grid for a few seconds. I have computer, monitor, modem, and router on this device...never have lost anything.

    Works great, save me while I was working and power went out. Gave me time to save my work and shut everything down. Also let me charge my phone while power was out. I would say i would have about 15 min of pull desktop and monitor time with the battery back up.

    The narrow design of this battery backup is what sold me. Easily sits behind the entertainment system. Makes it easier to conseil unit. Wish the spacing of the four plugs were a little bit further apart.
