They cost $6 at Home Hardware and maintain super low water pressure, which is a double win for landlords. However they’re very easy to modify. Remove the shower head and flip it upside down:
Notice that little hole in the top? That’s a simple mechanism that most shower heads use to restrict water flow.
Introduce this hole to your power drill. Use increasingly larger bits and test it in your shower until you reach a decent pressure. Enjoy!
