This UPS has been solid so far. I have my router plugged into it so I don't lose wifi whenever there's a power outage.

I have bought several of these, though not for the back up battery primarily. I needed clean filtered constant power. This does a great job a great price. You won’t be disappointed.

My old cyberpower back up system lasted 4 years. The battery portion of the system quit functioning. I was happy with the way it performed so I replaced it with the same unit.

After a small power loss we found out bearded dragons dislike the cold. We got this to help keep him warm until power comes back or we hit the generator.

After reading reviews, and looking around, I bought this not only for the quality, but the price was right as well. Not much involved in the set up and everything is straightforward.
