We bought this unit because we had chronic problems with the UPS (we have several machines at home that run 24/7) and we suspected it there are quality problems with the power supply. .Received this device yesterday. The included software installs easily and seamlessly on a Win 10 computer. It appears to be working correctly, although we haven't logged any power events so far (and we have no reason to believe it should). The only oddity we've noticed so far is that when plugged in, the 'Power Loss' LED immediately lights up, rendering this indicator useless. (Bring it together, Powertronics.) I wasn't sure how many stars to give as it hasn't seen much service yet. Left it for five as we are very happy with it so far.
