Flat or ripple?
Skip the taste promises.
Two base styles are available for the Flash 2.0. Here is what manufacturer information tells us. We have not tested either option.

Our practical view
Choose a base that fits your basket and suits your routine. We start with flat because it is a straightforward option to explain, not because we have measured better extraction. We do not recommend replacing a tool that already works merely to change its surface.
What we have not measured
We have not compared extraction yield, taste, puck removal, cleaning effort or long-term wear. Claims about those outcomes need evidence beyond the product description.
