I bought 2 of those of that guy, i think he sends them on the back of a donkey cause the take forever but he is nice enough to mark them a present so hmmm hmmm nobody adds to the price of it I can't tell you how good they are cause i've not used them. As far as i know there's a lot of home brewers using the same ones from the same guy.
Bought my last two off him . . . He even ended the second auction early (I wasn't paying the BIN price ) when I won the first and I got both for the same price. . . . Arrived pretty promptly as well, they work well . . . . Not that I have used them in anger, but they are set up to be used . . . just got some indicator lamps to wire in, and connect up the PIDs and I'm away with the Effin controller.
