The Timemore Chestnut C2 has stainless steel burrs which means it can be consistent across all grind size adjustments unlike other grinders with a similar promise. If you’re grinding for an espresso, aeropress, filter or even french press, it’s got you covered. I have one of these at home and personally I love it, it's also incredibly quick for such a small device. You can never go wrong with something like this.
