Here is a question from one fan.
I have an evolve XL just wondering how much actual shatter can it hold. And do I put it in the Center of the heating coils ?
Yes, you should drop it on the center of the heating coils.
Concentrate should be placed directly on the heating element. To prevent clogs, be careful not to overfill the chamber. A portion of concentrate about the size of a peppercorn is a good starting point. Using a dab tool to load the unit is recommended due to the stickiness of many concentrates.
