These new precision shower screens are specially designed to improve performance, enhance shot quality, and stand the test of time. They work on Slayer, La Marzocco, and Synesso machines. The screen gives off an even water distribution, allowing for better extractions, less channeling, precision and more body and roundness in your cup. Take a look at the video below to see for yourself!**Note: when back flushing with a detergent the coating on these screens will begin to breakdown.
