Ongrok Mini 4 Piece EZ Grinder – 2.2″

The Ongrok Mini 4-Piece EZ Grinder and the Premium EZ Grinder share the same core design elements: quarter-turn locking system, removable mesh screen, 33 triangular teeth, nylon O-rings, and neodymium magnetic lid. The only difference is size. The Mini measures 55mm (2.2 inches) in diameter, while the Premium is 63mm (approximately 2.5 inches). The Mini grinds less herb per load and accumulates kief more slowly due to the smaller chamber, but it is more compact and pocketable. The Premium accommodates a small humidity pack in its larger kief chamber. For users who prioritize portability above all else, the Mini is the better choice; for users who want more capacity, the Premium is preferable.

The quarter-turn system on the Ongrok EZ Grinder replaces the traditional multi-turn threading used to open and close the middle chamber of a standard 4-piece grinder. Instead of unscrewing the chamber multiple full rotations, the EZ system requires only a 90-degree quarter turn to unlock and open the storage compartment. A turn in the opposite direction closes and locks it. This prevents the common problem of chambers becoming stuck when resin builds up on the threading, and makes accessing ground herb significantly faster. The mechanism is intuitive: twist a quarter turn one way to open, a quarter turn back to lock. No special technique is required.

Yes. The 2.2-inch Mini EZ Grinder is specifically positioned as a daily carry grinder. The 55mm diameter provides enough capacity for a standard personal session, and the quarter-turn locking system makes it faster to use than a standard-thread grinder during repeated daily sessions. The removable screen maintains its performance with regular cleaning, and the neodymium magnet keeps the lid securely closed in a pocket or bag. Users who grind primarily for themselves and who prioritize pocket-friendliness over high-volume capacity will find the Mini EZ a practical and consistently performing everyday carry grinder.

To remove the screen, open the main compartment using the quarter-turn mechanism to access the interior above the screen. Locate the screen handle, lift it, and rotate it counter-clockwise to disengage the screen from its seated position. The screen can then be lifted out completely for separate cleaning. Soak the screen in isopropyl alcohol for 10 to 15 minutes, rinse with warm water, and dry fully before reinserting. To replace the screen, lower it back into the chamber base and rotate clockwise until it locks. The handle should be flush and secure when properly seated.

Yes. Despite its compact size, the Mini EZ Grinder includes a full kief collection chamber beneath the removable mesh screen. Fine particles pass through the screen into the bottom chamber over multiple sessions. Due to the smaller diameter compared to the 63mm Premium version, the Mini accumulates kief more slowly per session, but it still collects meaningful amounts over time with regular use. A small scooper is included for harvesting kief from the bottom chamber. The quarter-turn locking system does not affect kief collection, which occurs passively through the screen during normal storage and handling of the grinder between grinds.

Use the included brush to clear herb debris from the teeth after each session. Remove the mesh screen by lifting the handle and rotating counter-clockwise, then soak it in isopropyl alcohol for 10 to 15 minutes, rinse with warm water, and dry completely before reinstalling. Disassemble the grinder using the quarter-turn mechanism and soak the aluminum body pieces in isopropyl alcohol, brush away dissolved residue, rinse with warm water, and dry completely before reassembly. Wipe the nylon O-rings with a dry cloth. Regular cleaning after every few sessions prevents resin from building up on the quarter-turn mechanism, keeping the easy-open function smooth.
