1.Coffee Tamper with Sound Feedback – This impact tamper features sound feedback that signals when the optimal tamping pressure is reached. A clear 'click' indicates the perfect pressure for extraction, and the tamper automatically releases the pressure. No need to worry about force or timing—just press down, and the tamper will handle the rest, ensuring consistent tamping with every use. 2.Impact Tamping for Consistent Pressure – The impact force instantly applies high pressure to the coffee grounds, quickly forming a compact puck. This tamping method reduces the inconsistency of manual tamping and ensures uniform pressure with every use. It minimizes the dependency on the user's technique and touch, making it ideal for situations where efficiency and consistency are a priority. 3.Innovative 4-Spring Design – This advanced 58mm coffee tamper features a groundbreaking 4-spring system that ensures precise tamping. The horizontal spring prevents tilting, the impact spring maintains consistent pressure, the positioning spring adjusts to the required tamping height, and the reset spring guarantees accurate repositioning after each use. 4.90° Vertical Tamping – The base's horizontal cap is designed to prevent tilting, ensuring every tamp is perfectly vertical at 90°. This results in even pressure distribution, eliminating the risk of channeling caused by slanting. Additionally, the threaded 304 stainless steel base increases the area with the coffee grounds, enhancing extraction.
