I got this to deal with the inconsistent power in my apartment. I first looked at APC but then I found this one. I get more power and battery life for my buck and this thing is excellent quality. It is a little big but that is the battery. I have my 1000w PC, 23in monitor, modem and router hooked up to it and I can get 25min of battery power out of it!! The software that comes with it is great, it shuts down your computer safely when the power has been out for how ever long you tell it to, and has an option to turn off the alarm when the power goes out which is nice. The LCD screen is off and turn on when you push a button to see the data. This is nice because then you don't have your room glowing blue. Overall I am very happy with this product and would buy it again. Great value and quality for your money. 

Question: What is software?
Answer: The software that comes with is great
