Used for concentrates, the Taster turns the Genius Pipe into a compact oil rig that fits in your pocket and doesn't need water! It will not add to or affect the taste of your favorite concentrates. Genius Tasters are to be used in combination with the Evolution slider. The Taster fits down into the Genius bowl and features a groove underneath that functions as a lock when the slider is slid into place. This ensures a secure connection with the Genius Pipe.
