Spec, translated

The 'Durable stainless steel blades' specification confirms this is a blade grinder that functions like a small blender. It chops beans violently, not mills them uniformly, which is the primary factor limiting coffee quality.

Lab notes

The observations that actually change the buying decision.

This is a blade grinder, not a burr grinder. It shatters beans into inconsistent sizes (dust and chunks), which results in uneven, poor-tasting coffee extraction.

The motor has a thermal switch with a recommended 30-second run time. If it overheats, it requires a 30-minute rest, signaling a motor not designed for frequent or heavy use.

Its best feature is the detachable, dishwasher-safe SUS304 steel cup. This makes cleaning far simpler than on competing models with fixed cups.

The 50g capacity is sufficient for a standard pot of drip coffee, but the 'press-to-grind' control mechanism offers no repeatable precision.

Why you should buy

This is for someone who needs to grind spices or wants a very simple machine for coffee beans and prioritizes easy cleanup above all else. The removable cup is the sole reason to choose this over other sub-$30 blade grinders.

Why you should skip

Anyone seeking better-tasting coffee should save an additional $50-$70 for an entry-level burr grinder, as the difference in grind consistency is vast. Users who grind beans daily may find the motor's thermal limits frustrating.
