The only thing I can add is the hose. We actually kept the Sunline hose as it was more flexible then the one that came with our Oxy head as a kit. We like the shower head, but not the hose.
We bought ours in 2012, so do not know if they changed their older stiff hose to a more flexible one. Just mentioning it in case you find the same problem.
