精準單次劑量漏斗（附泵）

Finally, a hopper that actually fits my GS3 without any fiddly adapters — the single dose pump works perfectly for switching between espresso and filter grinds. The pump action gives consistent doses every time, which has honestly improved my morning workflow more than I expected.

The pump mechanism engages smoothly every time, making single dosing for my espresso routine much more consistent than my old setup. I’ve been using it for filter coffee too, and the switch between grind settings is effortless. Definitely a solid upgrade for the GS2.

The pump mechanism on this hopper feels incredibly solid, and swapping beans between espresso and filter is now a breeze. It fits my GS3 perfectly with zero mess, exactly what I needed.
