The 9-inch swing arm is of good length, but could be longer. It is not very easy to adjust though. The tightening screws are not strong enough to support the weight of the arm and showerhead. You need to tighten these very hard to keep the showerhead in place, so the "arm adjusts for personalized positions" statement isn't true, unless everyone has strong hands.
Otherwise, everything is perfect. The finish is great, it looks very good, and it will make you feel like, as much as a showerhead can, under the rain.
