Re: Shower head restrictor
If the restrictor is in the threaded portion that screws onto the shower neck sticking out of the wall, then it should come out. Use the tip of a pocket knife or similar small but strong item to get under the edge and pull it out.
If that doesn't work, then carefully go at it with a drill bit. Start small, maybe an 1/8" bit and test your work. If you like what you've got, stop, if you want more, drill a little larger hole.
IMHO, what good is a "water saver" shower head when it cuts the water flow in half which requires a shower twice as long to get the job done? Don't get me wrong, water saver devices are a good thing, but often times they are ill conceived, designed, and implemented.
