Keep up the Good Work,

This works great for keeping power going seemlessly in those rare occasions and switches back to AC mode after power is restored.

The APC UPS 600VA battery backup is working great.

Like many others, my unit just stopped working after 5 months

Set up was easy and both units seem to be working fine so far, again, I've only had then for two days

Easy to install the new boxes and they hold power very well with no problems and the battery backup works very well when there are storms and power lines that go down, etc

This isn't working well enough to not reset when using it with my stereo, combined they only have 300 watts, so this should have been fine rated at 550 watts, but this "reconditioned" apparently they didn't test it for peak wattage

I’m so happy everything worked the back up power works so well

Unit was working good, but at the second year of use (it only has 1 T.V. connected) suddenly a very high pitched sound alarmed the whole house

It is working very good 👍🏼

Boom this works perfect

and this allows me time to get everything shutdown without loosing a days work.

No product has caused me more headaches and lost work than this.

Worse, loosing power while working on web-based applications may cause data loss

Right now appears to be working fine we will see how it does when the power goes out

There was no surge the unit cut off then started to smoke with a continuous beep and now its not working

Never lose any work again.

Before getting this backup, if my power went out I lost my work.

Is working really good, this APC already save my TV Sony 50" and PS4 multiple times

This worked great as I took it out of the box, connected the hot terminal wire per the instructions, plugged it in to a standard outlet, and then plugged the modem into it.

It has worked well in both instances
