As far quite well, but could be a total of a little more stable. The parts can be not determine correctly because some internal threads are made of plastic, although the indication metal version in the product description !!! So for me, the part fully OK, I'm going to need it approximately 5-6 times per year. If someone wants to inserting the part for daily use, I would advise against more and recommend a more stable version.
