유레카 아톰 블로우 업 시스템 호퍼 및 뚜껑

The accordion design works perfectly for pushing leftover beans through the grinder, and the hard plastic lid seals tightly to keep everything in place. I've had zero retention issues since switching to this hopper.

I was skeptical about the accordion design, but it really does force every last bit of coffee through the grinder. The lid seals tightly, keeping grounds from flying everywhere.

The accordion hopper creates a perfect seal when I pump it, pushing leftover grounds straight into the bin without any mess. It snaps onto my grinder securely and feels much sturdier than I expected for the price.
