Know before you buy
The ThunderShot is designed for machines using a standard 58mm E61 group head. It is compatible with many models from brands like Rancilio and La Marzocco, but you should verify that your machine uses a 2-ear portafilter system before purchasing.
A bottomless portafilter exposes the underside of the filter basket, allowing you to visually monitor your extraction in real-time. This helps you identify issues like channeling or uneven tamping, making it an essential tool for refining your technique.
Yes, the ThunderShot includes a precision-engineered filter basket with an 18g capacity, which is ideal for pulling standard double shots.
The handle is crafted from moisture-resistant walnut, but it should not be submerged in water or placed in a dishwasher. Simply wipe the wood with a damp cloth and dry it immediately after use to maintain its finish.
Because there are no spouts to direct the flow, any inconsistencies in your puck preparation can cause espresso to spray. While this is a great way to diagnose your technique, you may experience some splashing until you master your grind size and tamping pressure.
The body is made from professional-grade SUS304 stainless steel, which is highly resistant to corrosion and heat. The handle is made from solid walnut wood, providing a comfortable, ergonomic grip.
