	I have checked mine against a good electrodynamic wattmeter both for
resistive loads and for reactive ones with power factor as low as 20%
(as low as I could simulate with a capacitor bank) and the calibration
seems close enough that I can't tell which is more accurate.  Seem to me
to be a good buy.  Don't have any idea as to their waveform sensitivity,
however.
