er6n subsequent pick-up heating

hi hello the winter is in front of the door, and I have recently had a used he6n vintage 06-09 at my home. the cold pfoten trues are included in the price, but I would like to change that now. as long as there is no snow on the road I would drive through the whole year with the motorcycle to work, so grip heating would be a real enrichment for me. now I wanted to know which experiences you have made with which systems, and which I do not fall into any case ka ufen should… pricewise I would rather not go over 60 euro, except mann notice in temperature and processing quality a big difference. also it should probably be removable again, so that I do not have to buy a new one again with a new motorcycle. so, I’m curious what comes so lg stefan
