I ordered 1 1/2 years ago 5 of this Gurtwicklern and had now the 2nd return them. But kudos to Amazon. A Gurtwickler broke down after less than a year, no longer function after it has. A week already refereed at least at high frequency. Now the 2nd Gurtwickler has made more and more crashing lately and spread again and again. Nevertheless, I find the equipment well, only 40% loss is a little too much.
