Impact Coffee Tamper 4spring system for reliable tamping: horizontal springs prevent tilting, impact springs maintain consistent pressure, positioning springs adapt to the required compaction height, and reset springs ensure precise repositioning after each use. No extra adjustments needed to achieve even and thorough compaction every time. Upgraded hollow design for efficient tamping: the hollow construction combines impact force and constant pressure, saving effort while ensuring consistent tamping pressure. The ergonomically designed handle fits the palm for comfortable use, even during frequent use. A builtin sound feedback click confirms when the preset pressure is reached for consistent results. Rippled base for extraction: a rippled base with a concentric ring pattern improves espresso quality. The metal threaded base increases contact surface between water and coffee grounds, enhancing extraction. The indentation pattern helps control water flow and saturate the grounds evenly to achieve better flavor. Professional quality and durability: built with a sturdy aluminum alloy structure for strength and longevity. It resists corrosion and oxidation from prolonged use, helping prevent rust and supporting dietary health.
