I stumbled upon this YouTube video that compares the Creality Pi and the Sunlu S2 and a much older model of a dual Eibos dryer. His testing methodology has some serious flaws. As an example, he speaks to the unevenness of heating but he doesn’t do any hard testing other than the cool IR camera which doesn’t address the faulty hygrometers. He also went through the trouble of weighing the desiccant before drying but failed to weigh it after. However, he still came to similar conclusions that I found to be true when I did my bake-off between Sunlu and Creality that I linked above.
