Bought one a few months ago. I specifically like the concept of using a 24bit ADC to grab the voltage drop over a length of cable and calculate the Amp draw without having to break the circuit.
I also wanted to compare it to the Fluke 289 for logging. I find it is slower than the fluke.
So it sits in my drawer(with the battery uninstalled) waiting for somebody to want some kind of transient monitoring on their power inputs. I don't think of it much in day-to-day use. with no screen it is somewhat limiting.
