T12 controller fitted, irons modified with 4 pin plugs to suit and I can't say how good it is to be able to read clearly the display, far better then the Blue OLED controller and its also amazing just how close these two stations are now with the displays reading almost identically for the voltage being supplied to the element, the regulation of the power being consumed by each is within 1% of each other and the internal temperature measurement is within 1C.
The temperature calibration is almost the same setting as well, both stations maintain the temperature pretty well and measure within a few C on the Hakko 191 gauge, so I'm a happy bunny.
