Hello There. I regret to say that I am disappointed with the shower head. Not like in Question and Answer to the article indicated 1/2 "M28 was a water connection to the shower head mounted is absolutely uncommon in the shower area. Fine thread / external thread. War help in case of a gas / water fitter, a Bauhaus and a bathroom outfitter, no one could . Article goes back.
Otherwise, the article looked outwardly sensible. But for me just not to use.
