The ROFFU was designed in Los Angeles, California, United States, and is manufactured in our facility in Shenzen. Made in an ISO 13485 Facility for Manufacture of Medical Devices.

The additional accessories for the Starry 4 are a glass adapter, glass bubbler, ceramic adapter, dosing capsule, concentrate metal pad, wax cup and 18650 2550mAh battery.

The maximum temperature is 220℃/428℉, and the minimum temperature is 100℃/212℉.

XLUX ROFFU uses a removable 18650 3200mAh (Lithium-Polymer) battery.

Please use the provided USB-C charging cable or other standard Type-C charger to charge the device, and please ensure the input is no more than 5V/1A. Or if you have other working 18650 3200mAh battery, you can install it into the device for use.

No, we do not suggest operating the device while charging.

When charging the device for the first time, we recommend charging for more than 6 hours. Later, if you use a 5V/1A charger, 3 hours is enough to charge the device fully; if a 5V/500ma charger, 4-5 hours will be needed; if a charger exceeding 5V/2A, the device will stop being charged. The XLUX ROFFU owns a automatic charging protection from the chargers exceeding 5V/2A.

The battery can be used at least 20 sessions under the 3mins session and the highest temperature of 220℃/428℉after each full charging. The lifetime of 18650 3200mah battery is 350 times of cycle use and charging. The battery will decline after the 350 times of charging use.

The capacity of oven bowl/heating chamber is about 1ml, and the size is 0.43*0.93in/11*23.6mm. Our suggestion is do not load too much or overload the materials when using the device.

The XLUX ROFFU uses a convection glass oven/chamber (also will have an extra stainless steel one) to heat up and vaporize the dry herb materials.

It really depends on user’s habit. General advice would be to lower the temperature for lighter sensation and increase the temperature for heavier sensation. For XLUX ROFFU, temperature ranges from 100℃ to 220℃ (212℉-428℉). Click the “+” button/ or the “-” button to let the device reach your favourite temperature.

Usually it takes 10 seconds of heating up to half temperature. If you need to heat up to the highest temperature it may takes around 20 seconds.

There are few ways to ensure dense vapor producing:

Temperature: The higher temperature, the denser vapor will be.

Heating time: More heating time can help to produce denser vapor.

Inhaling: Slow and long inhaling will help you get much denser vapor, and make the vapor taste better.

Materials amount: Please don’t load too much/overload materials. Too much loading may cause uneven heating and even block the filter component and mouthpiece, so that the vapor cannot pass to the tip smoothly.

Materials quality: If the materials are wet or the quality are too bad, not much vapor can be produced.

Hold the up button and down button at the same time for 2 seconds.

• Mouthpiece: Ceramic ZirconiaChamber: GlassFilter component: Stainless steel & CeramicAirflow box: Ceramic ZirconiaThe materials of these components are certificated and pass the food-grade material inspection. Besides, the 100% isolated airflow path can help users to get a cleaner and purer vapor.

The airflow path is made out of clean and certificated ceramic. Besides, it’s 100% isolated from electronic or plastic components.

Yes, the filter components are removable and can be removed with a gentle dig.

We DO NOT suggest using any wax & oil/liquid for the XLUX ROFFU.
