"A cheap way to smash coffee beans into dust and chunks, not grind them."
The 'Heavy-duty stainless steel grind blade' signifies the product's core mechanism: it's a high-speed chopping blade. This design is inherently incapable of producing the uniform particle size required for a balanced coffee extraction.
This is for someone who finds pre-ground coffee stale and wants the lowest possible upfront cost for a marginal improvement in freshness. It is also a functional, inexpensive spice grinder, provided it is never used for coffee.
Anyone serious about the taste of their coffee should skip this. The inconsistent grind will introduce bitter and sour notes that no brewing method can fix. A budget manual burr grinder for twice the price offers a significant upgrade in quality.
