I recently bought this item.   I like the look and design.  All was good until I tried to mount on the shower extension fitting.  The threads would not grip and looked like they were too wide.  If I pushed hard on it I was starting to cross thread the fitting on the shower head.  I put the old shower head back on the extension just to check the threads.  Threads on the shower extension where fine.   Do you make a metal fitting for this shower head.  I read multiple reviews where this was a common theme.  Don't want to return this just want it to fit.
