I got mine today also, and feel the same as you. I think this will have me using my GH on the go more. I'm thinking
@DDave Mi V2 cooler with this will make a nice dry/cool combo on the go with no extra parts needed!
As for the screen, mine looks like it may have been pushed in from the mouthpiece end? Looking inside the mouth piece, the screen looks like it has 3 "tabs" pushed up around the edge as if they were being used to create something digging into the sides to hold it in place. Like inexpensive spring steel fasteners that you push over rods and such. This would match the 6-7 pairs of lines scratched into the inside walls. These lines are the same width apart as those tabs. I can feel ever so slightly that they are scratches, but I don't think they will cause any problems including extra cleaning. They're not deep enough.
I'm guessing these early batches will have a few remnants of the assembly learning curve.
I'm not convinced that they open the airpath much either. I did a very unscientific test by swapping them back and forth and drawing multiple times directly thru them (not thru glass, etc.). I think the inlet is where the blockage is, if I start to pull hard, it has a lot of noise there......
The GH with PFE pairs beautifully with an Orbiter. The small size and hoses are really matched to the GH and its airflow. This could easily replace my Evo/Hydratube or HB Maxx/Hydratube night side table setup. It takes up almost no room, not much more than a can of soda and still delivers the clouds.
It's definitely a keeper
