"It has the skeleton of a $500 grinder for half the price."
The 64mm flat burrs let the grinder spin slower to produce the same amount of grounds, which reduces heat and preserves the coffee's delicate aromatic compounds.
This is for the hobbyist who prioritizes on-paper hardware specifications—namely burr size and metal construction—over brand legacy and proven support. It's a value play for someone willing to trade the risk of an unproven product for access to prosumer-level features.
Buyers who need a grinder that is guaranteed to work for years with accessible support should consider an established brand. The unproven motor and long-term electronic durability are significant question marks for anyone not willing to potentially tinker or troubleshoot.
