Mine is an es9 'hybrid' plotter so possibly a generation later than yours and no problems after a few years so far. I only seem to use the rotary controls in rough weather when the boat is bouncing around making the touch screen difficult to use.I beg to differ. My E7 plotter stopped responding to the touch screen on a number of times. When approaching Scapa Flow the screen had got quite wet as it was a force 7 to 8 blowing and my hands were soaking wet. It took a lot of kitchen paper to dry the screen and fingers to get it to work again. When you are singlehanded and the ram bracket on the tiller had sheared rendering it unuseable, as I was, it was not fun. I have also had the same problem with my iPhone SE 2020.
