Recieved OK. Tested from 5V to 3.07 and was accurate and stable. Didn`t warm but it`s a small diference in voltage cut (just 2 volts). To adjust it I turn the little gold screw (top on the blue adjustable capasitor) oposite from clock turn, it needed a few turns to start the value of voltage to drop. Very easy, very small, solders looks good. I will use it to drive 3.1volt - 1,6 Amps Step Motors.
