Look carefully, they do not appear to be the same device. The one I bought has two pots to make the device act as either a constant voltage regulator or a constant current regulator. Plus mine reads alternatly switches to display both voltage and current in the display. The one you bought appears to be just an adjustable constant voltage regulator with a voltmeter only display. I've bought some regulators like that for $1.52 each with free shipping also, but without the cool display of course.
