Love the MD showerhead, very effective filtering our hard well water! Used a different brand of filtered showerhead for a couple years but after every one of them failed/developed non repairable leaks, it became time to try something else. It appears MD’s design is much better and don’t see any problems with that, although time will tell. Going on three weeks and all is well! Long haired women of the family love it, noting their hair and skin feel wonderful! Believe the filter is top notch! Going to order one for second bathroom.
