I've had airflow problems with mine as well. I've had my Dynavap M for a month now, and I've been trying to use it daily since, because it uses so little, but I may soon retire it, or toss it in the trash.

It's been such a pain in the ass for me. It's ridiculous, I'm glad I have a Pax 2 for backup. If I could go back I would have never purchased. All the great reviews and messages from others got me to try. It's funny because they have a 2019 model now..

One thing users have been saying is to make sure you don't pack your herb in and let it be more loose. Right now I finished cleaning my device and have nothing in the chamber and still get 0 airflow. I hope it helps you, but it sounds like we're on the same boat.
