Tapping with a conventional tamper easily creates uneven coffee extractions because the baristas’ tamping force is not uniform. Even for the same barista, the tamping force is different each time. Therefore, MHW-3Bomber has researched and created the Flash tamper to provide a constant tamping force, helping espresso cups maintain the same quality. 

Tamper Flash uses the original three-spring design: 

• Spring 1: Helps the tamper automatically recover after compression
• Spring 2: Helps the tamper stand upright, giving the compression direction a vertical direction to create even compression force.
• Spring 3: Maintains a constant compression force of 30 pounds and provides audible feedback via a “click” to signal that you have achieved the required compression force.
