This was relatively easy to install. Put the set screws on before attaching to wall and thank me later. That was the only step that gave me issues. Paired this with a delta cartridge and valve. Good even pressure on all settings. Double sided tape for install is golding nicely, will attach to tile wall if the tape fails. You can use rainfall and shower handle at the same time, just rainfall, or just showerhead. Very nice and worth the price.
