I have no doubt an OE Bosch module is reliable. But these copy of a copy distributors are not. Module aside, the lack of adjustability, poor bearings, sloppy tolerances, aren't worth the risk. We got in a batch of these years ago to test in a shortage, I scrapped or returned 95% of them. Wouldn't even consider trying them again. Every country has its good and its bad, despite what continent they are on. These, are bad.
