    This device used to be big, but this particular item is really compact. That makes it convenient when you don't have a lot of space under your desk or behind the the entertainment center. Well designed to fit 8 power cords, including those power cords like the apple and Asus king, they are bing in lenght. Maybe not so convenient for those wide power connectors like those from 3.5 external disk. Price is very good, I just hope the small battery included will last long and wont run out of power before the time specified on spec. it can be laid on the floor or hang it to the wall with two screws provided with the package. The cable is very long, make it convenient to reach a power outlet that is far from your equipments.

    Wanted a small backup battery for my home router and modem, to avoid power interruptions when working. Seems to do the job well so far.

    Can turn off the alarm, so it doesn't need to wake you up in the middle of the night. Is silent even when it is running on battery power. Can stand its tall side up to save more space. Battery is reasonably easy to access for replacement, but you will probably not find a battery with the right dimensions, so need to cut the side out of the unit to fit a new battery

    Using this to power computer, two 32” curved monitors, stand up desk and other peripherals. I only have my purposely unplugging the UPS during setup to go by, but the power off alarm is quite noticeable; a good feature.

    Great for what I need. Haven’t had a storm yet but got it so that I have time to shut everything down just in case the power goes out. I like how many outlets it holds! I think it was also well priced!

    Small and compact but has the ability to do surge protection for devices as well and back up for power loss WITH 2 usb charge ports. Great price and value! Plug in charge for 8hrs and you’re good to go!

    Simple battery enabled surge protector. Protects from electricity surges and keeps devices on for about 5 minutes. Also has an alarm style warning for when there are issues.

    Well, so far so good. I've already had a power surge and it kept all my electronics (computer, monitors, external hard drive) from frying. SO - I'm happy.

    Great UPS for a low-profile SOHO environment. The fact I get 4 battery ports and 4 surge ports for less than $60 is the biggest reason I bought this product. The quality and ease of use is why I'd buy it twice.
