The GR8TR's patent pending interchangeable grinder plates have created the first and only grinder with the ability to customize the consistency of your grounds. Two seperate storage compartments allow you to store more than just one blend and / or style of grind. The lid and base of each GR8TR can be easily combined to create a pocket sized storage "puck" so you can grind at home and take your blend anywhere with ease. Kannastor's innovative Micro-Teeth and Press (MTP) design has many benefits over traditional style grinders. Effortless grinding action - The MTP design creates and utilizes stronger "micro-teeth" that shred from the top and the bottom while simultaneously gently pressing through grinds. Since the MTP design requires far less torque and strength to complete your grind, it allows users with medical conditions and less physical strength to grind almost effortlessly.
