I'm used to everything I want vorherzu installing, check! The faucet (mixer) works - no need to return - but I am disappointed with regard to the quality of workmanship !!! The design: everything was perfect, well thought out, works flawlessly! Processing: very nice to look at ... but a torn half thread on the cold water side? That should be normal? ... I can not imagine ... but it works and therefore keeps still ... no recourse to return or exchange! My advice please ??? Stay away from this manufacturer! It's when it comes ... and if not ???
