RUI PORTABLE ELECTRIC COFFEE GRINDER
Grind beans with RUI portable and effortless

PATENTED INTEGRATED BODY DESIGN
From the very beginning of its design, RUI has abandoned the traditional three-stage body design and adopted an innovative integrated body design. We believe that grinding coffee beans is a high-frequency operation, and it is very inconvenient to disassemble it every time you grind. Therefore, in the initial design of RUI, we adopted the same body structure design as professional electric coffee grinders that cost thousands of yuan. You can directly put the beans into the bean hopper without the need for complicated disassembly and assembly. Grinding coffee only requires opening the top cover, making the operation simpler and more convenient.

GRIND WITH RUI AND SIGNIFICANTLY ENHANCE THE FLAVOR OF YOUR COFFEE!
zeroHero's original HG6-38 "cut first, then grind" two-stage grinding burr, combined with patented integrated body craftsmanship, significantly enhances the "aroma and sweetness" of the coffee.

INNOVATIVE ADJUSTABLE GRIND SIZE FUNCTION FOR EASY OPERATION
With different grind size options, you can easily adjust the grind size with just one turn, eliminating the need for 20 or 30 different settings. It can meet the requirements of various coffee brewing methods, such as espresso machines, pour-over pots, siphon pots, moka pots, and cold brew pots.

GRIND WITH RUI AND UNLEASH THE FULL "AROMA AND SWEETNESS" OF YOUR COFFEE
With professional grinding by RUI, the coffee particles are more even, the oils are richer, and there is less flavor loss, making the "aroma and sweetness" more pronounced. You said:

FAQs
Please read our FAQs page to find out more.
Do LAMOSE products come with a warranty? If so, what does it cover?
All LAMOSE products come with a lifetime warranty. This covers any manufacturing defects in the material or workmanship under normal use and maintenance. Please note, this doesn't cover damage caused by accidents, inappropriate use, or wear and tear.
What materials are LAMOSE products made from?
LAMOSE products are made from high-quality, food-grade 18/8 stainless steel, renowned for its strength, durability, and resistance to rust and corrosion. Our lids are made from BPA-free plastic with a silicone seal to ensure a tight fit and prevent leaks. Our materials are carefully selected to ensure they are safe, sustainable, and able to keep your drinks at the perfect temperature.
How long will LAMOSE drinkware keep my drinks hot or cold?
Our LAMOSE drinkware is designed with advanced thermal technology. For our hydration and beer can collections, cold beverages can stay chilled for up to 24 hours. Hot beverages in our coffee collection can stay warm for up to 12 hours. However, the actual duration can vary based on the starting temperature of the drink, the outside temperature, and how often the container is opened.
Are LAMOSE products dishwasher safe?
While our LAMOSE drinkware is made from durable stainless steel, we recommend hand washing all our products to maintain the integrity of the insulation and the longevity of the custom engravings. Using the dishwasher may affect the insulation properties and could lead to fading of the personalized designs over time.
Can I microwave my LAMOSE drinkware?
No, LAMOSE products should not be microwaved. Our drinkware is made of stainless steel, which is not safe to put in the microwave. Microwaving can damage both the product and the microwave.
How should I clean my LAMOSE drinkware?
To clean your LAMOSE drinkware, hand wash with warm, soapy water. Rinse thoroughly after cleaning and leave it open to air dry. Avoid using bleach or abrasive cleaners to maintain the integrity of your drinkware and its custom design.
