The still performs fine, Other than the dephlegmator. I have a hard time controlling the temperature above the dephlegmator, due to having almost no water flow. If I open the tap to more than a leaking faucet,it cools down too much. The controller is garbage. One half controlles the power to the amperage display, but doesn't power the element, the other one powers the element,but doesn't show the amperage being supplied. I also ordered an extra element and controller, and apparently it was a good idea, because the one element was not working at all, so I switched it to the extra one and it works. It's also good that I ordered the extra single controller because the first one only half works but no display. So I ordered 2 new controllers from Amazon, and they both work. So I can only give a 3 star rating.
