Adjustable Depth with Clear Scale Marking Built with visible depth scale indicators, it supports free depth adjustment to fit different portafilter basket sizes. Extremely user-friendly operation allows both beginners and seasoned users to set ideal working height effortlessly. Even Ground Distribution for Consistent Extraction Simply rotate the dual-head leveler gently, you can flatten uneven coffee grounds inside the basket thoroughly. It eliminates unfavorable brewing variables, delivers uniform water penetration across the whole puck, and brings well-balanced, rich-tasting espresso shots steadily. Food-grade 304 Stainless Steel Construction Both working heads are crafted from premium food-safe 304 stainless steel. Rust-resistant, high-temperature durable and harmless to human health, it ensures long-term safe repeated use. Effectively Fix Uneven Ground Issues Ground coffee often ends up uneven due to static clumping and inconsistent filling habits, forming uneven loose-tight density and uneven surface height. This professional distributor breaks up clumps and smooths the grounds, creating uniform density throughout the coffee puck. Minimize Human Operation Errors Manual leveling easily causes uneven pressure and angle deviation, leading to unstable brewing results. Featuring mechanical rotating leveling blades, this 2-in-1 tool greatly cuts down manual errors and greatly boosts brewing repeatability. Combined Use Optimizes Puck Structure & Brewing Efficiency Use the distributor first to smooth grounds before tamping. The matched working procedure reduces internal cracks inside coffee puck and builds stable compact structure. It lowers espresso extraction yield fluctuation by over 30% for more steady flavor performance. All-in-one design saves cost and space, no need to buy separate distributor and tamper individually.
