@Momor , same deal with your unit as
@Vapin in the usa. Nothing to be fixed and it looks like it is the packing, grinding style or type of herb you use. Sorry it took few extra days for our technician to get to your package to make a video but he made a video for you which shows plenty of vapor even at 320F. I will share it today with you so you can watch. If you have further questions or concerns, please let us know so we can show while we have your unit here. Otherwise, please confirm and we will get this out to you.
