A worthy product.
This is a great little grinder. I roast my own beans, grind normally with an electric, and brew with Aeropress. This is for travel.... Light, compact, not used everyday, and easy to clean. Works just as expected. My only less than 5 stars comment is absent guidance on reassembly after cleaning and a washer fell out. Customer support was 5 star in guiding me. Well done Simcoker!

Game Changer. Great for backpacking
This is a game-changer for coffee enthusiasts. Its 304 stainless steel construction ensures durability, while the ceramic burrs deliver consistent grind size for a perfect brew every time. The compact size makes it ideal for travel or small kitchen spaces. The inclusion of a cleaning brush and storage pouch adds convenience to its already impressive features. Whether you're at home or on the go, this grinder delivers exceptional results. Highly recommended for anyone serious about their coffee experience.
