I bought the unit on 2020/November/6th. I use it to run the Optical Network Terminal, or ONT. That device supplies an internet and phone connection. The Eaton 5SC 500 fills the role of a backup power supply that used to be provided by my internet service provider. Now when utility power fails the ONT continues to operate normally. With it's sine wave output the Eaton is compatible with the outboard ONT power supply. Estimated run time with a new battery is over an hour. More than long enough for me to report the power failure. I like the very short transfer time of 4 ms. So the chance of drop out during a transfer is virtually eliminated. The Eaton was so reasonably priced I bought a second one nine days later for my Synology NAS. Today is 2021/August/30th. Both units function perfectly. I like the display screen that shows you the status, operating mode, battery state of charge, and load in watts. After a while the back light for the display goes out and makes the unit less obtrusive. But the display is still on. Just shine a flashlight on it and you can read it. The only time the display actually turns off is when you switch off the unit and there is no supplied utility power. When utility power does fail it is quick to transfer to internal battery power and keep the protected equipment running. It does beep when this happens, but you have to be close by and the room has to be relatively quiet or you won't hear it. This unit does not have a fan in it so it's very quiet. When you unpack it you need to remove the front cover and connect the internal battery first before you do anything else. The quick setup guide shows how to do this. It was relatively easy for me to do. The unit came with some software on a CD and a USB cable. I'm not using these as neither unit is protecting a computer, so I have no idea how good or not the software is.
In the future If I needed to replace the Back UPS I'm using for my desktop computer, I will be looking to buy a bigger version of this one.

Had high hopes, only be left with a partially working device
I recently purchased the S350 with the hopes of testing it out with simple devices (switch, modem, & HUE hub). I connected the battery before I plugged in the device and plugged it into the wall for 48 hours. When I did this, the device beeped quickly, then displayed a green power light and red light below it. After that, the lights went away, there was a long tone, and then the red light started flashing. It then started beeping every few hours. I managed to stop the beeping by pressing the power button.After the beeping, I pressed the power button once more to turn on the device, nothing happens. I can plug devices into the surge protection side and have them work. But when I plug them into the battery backup/surge protection side, they do not work. The circuit breaker is not tripped and I am unable to use the device. However, when I unplug the device and press the power button the green light comes on.I then figure I'd give contacting Eaton a shot before I contacted Amazon about the item. No reply from Eaton. When I contacted Amazon about the issue, they also tried to contact Eaton but were unable to reach them.
