@esk8me, welcome. I for one have been using my single 6.6 ESC for over and year and about 1200km and haven’t had any failure. So I’ll continue buying (in fact did on Black Friday) please refer to this poll to see the failure rate.
People who had lost money by using your product (maybe their fault or faulty product) are going to be mad at you on this forum. Just treat it an input.
