We needed the shorter arm to make this fit. I didn't realize that for awhile that we could so it made for a stressful few days. It also took forever for them to mail the arm. (About 2 weeks) that arm was about $40 dollars extra as well. 

The water pressure isn't very good and it's not completely installed yet. 

But it is beautiful and looks so great. I love that it just fits the existing plumbing and u get a higher shower head out of it.
