1. What roast levels is this grinder suitable for?
   EDGE Mini is mainly designed for medium-light to medium-dark roasted beans.
   For espresso, medium-dark or darker roasts are recommended.
   For pour-over, medium-light roasts are recommended to fully showcase fruity acidity and floral notes.
2. How do I adjust the grind size?
   There is a dial-style adjustment ring at the bottom of the body; turning it clockwise makes the grind finer, while turning it counterclockwise makes it coarser.
   For first-time use, start from the middle setting and fine-tune according to your brewing method.
   As a guideline, each click adjusts one “micro step”; you can calibrate using the sound, feel of the grounds, and extraction time.
3. Battery life and charging
   Battery life: One full charge supports about 50 grinding sessions.
   Charging: Use the included USB‑C cable and a 5V/2A charger.
   Battery indicator: Press and hold the power button for 2 seconds; flashing red means low battery and it’s time to charge, while solid green means fully charged.
4. How to clean and maintain it?
   Daily care: After each use, run the grinder empty for 1–2 seconds to clear residual grounds, then use the included brush to remove remaining coffee dust.
   Deep cleaning: Once a month, remove the upper weight and hopper, wash and let them dry completely before reassembling; do not soak the burrs in water.
   Avoid moisture: Keep coffee grounds dry and never rinse the burrs or inner chamber directly under running water.
5. What if the grinder makes unusual noises or the particles are inconsistent?
   Unusual noise: This may be caused by grounds getting stuck; turn off the grinder, remove the hopper, and clean thoroughly, then make sure all screws are tight.
   Inconsistent grind: Check whether the burrs are dull or misaligned; if you use the grinder frequently, contact the manufacturer for inspection or burr replacement.
6. Can I take it on a plane / use it outdoors?
   Air travel: Because it contains a built‑in lithium battery, follow your airline’s regulations for checked baggage; it is not allowed in carry‑on luggage.
   Outdoor use: The lightweight design makes it suitable for hiking and camping, and it can be charged via USB‑C using a power bank.
7. Warranty and repair
   Warranty: Within 12 months from the date of purchase, manufacturing defects are covered by free repair service.
   Service locations: Please contact Sharen8 customer support to arrange service at the Mong Kok store or an authorized service center.
