    This is my second time I bought one of these but this time I got two. Now I have the computer and other items in the room plugged in and the second one has the big screen and all the entertainment center stuff plugged in. Already helped when power went out and gave us time to turn off pc and gave us time to watch the news and see what the weather was doing. Just great to have to keep over loads on TV's and computer and other sensitive electronics.

    Works well but it would have been nice to have alarm silence and a few other features that the last generation models had. Still it works well for a reasonable price

    This is a good value battery backup. I have not had a lengthy power outage to fully test the unit but so far so good.

    Does exactly what it is supposed to. I would take off .5 stars because the software doesn't work the way it should for notifications in email. Finding documentation is pretty difficult because there are several different versions and the most updated version has the issue.

    I own 3 of these They are a Quality backup power, It allows protection for our expensive equipment, As well as great backup time. I used this for different application. We have saltwater tanks It allows you to run water circulators, when the power goes out. We got to test it out when the electricity was shut down for repairs. Worked perfect !! Compared to the cost of the backup unit , the corals cost 10x as much.

    I get a lot of short power outages, no longer than two mins in my area and this kept my PC up with no issues. For reference, I am running a PC with a 4070 and 5800x. The power supply that I had on it was 850W. This is exactly what I needed.

    A great source to protect your equipment. 3 hours after hook up we had a brown out and this saved the equipment.
