About This IMPROVED CONSISTENCY – With a design that achieves the same tamp every time. The amount of pressure you apply is simply controlled by a spring inside the tamper itself. Comes with 3 interchangeable springs to suit your preference. Titanium PVD Coating - This low-static coating is harder and more corrosion-resistant. Also significantly reduce the amount of ground that sticks to the tool after each use. RIPPLE BASE - Created to minimize the risk of a doughnut extraction, the indentation on the coffee bed made by the ripple tamper allows controlled water channeling and even saturation of the grounds. UNIQUE DESIGN - Our coffee tamper is spring-loaded and does not require additional adjustments. It has an ergonomic handle with a comfortable grip that allows you to push ground coffee easily. SUITS 54MM BASKETS - The 53.3mm base is designed to fit 54mm Breville / Sega Portafilters (Suitable models including the Barista Express, Pro, Touch, Bambino Plus, Infuser, and Duo-Temp Pro).
