Wanted to share some reflections on Pax 2...
I have acquired all the accessories (including the factory half pack lid) to test this unit in multiple configurations. I had a good experience with customer service over an issue with not being able to change temps. Cleaned my defective unit, returned it for inspection, and promptly received a new unit with a new 10 year warranty. It has functioned perfectly since it arrived. So, happy with the support.
My main complaints are inefficiency, harshness of the vapor and the smell. To me the key regardless of how you configure is to keep the airway tube completely clean and the mouthpiece channels clean as well. I have the after market steel rod that makes it easy to clean with alcohol. I suspect many complaints about draw difficulties are a result of some obstruction in that tube? It takes very little residue to create a restriction.
I initially liked the NewVape screen because it does improve airflow and makes it easier to clean the airway tube. Easy in and out and easy to clean. I started thinking too much airflow might not necessarily be a good thing.
So, I went back to a complete factory configuration (flush mouth piece, factory screen, and factory oven lid. Perfectly clean as I described. Material ground fine with a Lift Innovations grinder. Packed well. Temp levels 3 and 4 produces very good vapor and good airflow. Wondering if Pax engineered the heating element and oven to work best with that think screen and factory flat mouthpiece and oven lid?
Smell can be dealt with with end caps if needed. Think limits of conduction are the reason for perceived inefficiency.
Probably a good matra for everyone is...to keep a clean vape! Helps efficiency and most likely longevity..
