Stop uneven extraction ruining your morning espresso.

Compatible with 51mm, 53mm, and 58mm portafilter baskets, this magnetic needle disperser is a must-have upgrade for any home barista or coffee enthusiast who demands consistency in every cup.

Why Even Distribution Matters

Uneven coffee distribution in your portafilter leads to "channelling" — where water finds the path of least resistance and under-extracts part of the puck while over-extracting another. Using a needle distributor before tamping ensures every granule of coffee is perfectly positioned, delivering a balanced, rich, and consistent espresso shot every time.
