The Kuissential EvenGrind coffee grinder is a machine that allows you to enjoy controlled and consistent ground size at an affordable price.
The grinder's secret is a removable cage that effectively stabilizes its burr. Rather than using a mounted axle mechanism, this machine has a removable cage that acts as a bearing for one end of the axle. Once locked into place, the cage stops the burr from moving, effectively reducing variation in grind zie.
The Kuissential EvenGrind coffee grinder is currently the subject of a Kickstarter campaign, with a pledge as low as $30 sufficient to get you one of these if and when the product actually hits the market.
Considering that many coffee grinders are expensive, this inexpensive alternative is sure to find a cosy niche in the market.
