Vitor was able to help identify the problem, but he was unable to fix my immersion heater switch properly, because he was not prepared, the new Neon switch did not fit, and he told me it was the cable got too short, but later I found out that it was not true, the Nero switch he brought with him did not have flew outlet, so he could not mount the switch properly onto the wall regardless of the cable length got shorter during the fix. I can accept everything else, but I cannot accept honesty issues. So no, I would not recommend him.
