Hey, I just got my Pax and I'm experiencing the EXACT SAME problems. To be more specific, here's my take on the situation.
The new mouthpiece just ain't right. According to b00bs, his Pax mouthpiece is completely firm and he has an earlier batch one. I contacted Pax support the first day after I talk with b00bs and I got one of the worst CS experiences of my life haha. The rep told me to go buy a new mouthpiece if I think it might cause problems. I asked if he/she could confirm with one of their Pax's that it jiggles a ton and they said no, they don't have any to test with.
I mean, I don't mean to sound like I have a brain, by why doesn't PLOOM compare and see for themselves and let me know if their mouthpieces exhibit the same issues I have so I can either, 1. get my mouthpiece replaced if my symptoms seem unusual or 2. be rest assured that my Pax is normal. How does the CS agent not have access to a Pax to let me know?
After a week, this shit starts happening. The mouthpiece starts exhibiting all the problems I list below. The only way to fix this is if you clean the mouthpiece tip (the connector) and you clean the metal vapor chamber outside with iso, the Pax will work PERFECT. Brand new, no joke. The mouthpiece will still jiggle, but it won't cause any interference with the device use.
So, I've seemed to find a temporary solution. It looks like the mouthpiece gets messed up by resin the most, espicially when it gets on the outside of the tip of the vapor chamber. I can easily wipe it off with a q-tip and iso and be done. But, I risk the chance of messing up my temp button (which is another wtf). Also, the goopy resin will start to appear after 4 sessions of about .4-.5. This is simply too much maintenance for my taste; I seriously think there's a design flaw with the (new batch of) mouthpiece(s).
Described symptoms: of (new) mouthpiece:
Mouthpiece won't pop up:
-Mouthpiece will stay in the down position and require fingernails to pry out, or eventually over 5 min it'll loosen up and slowly creep up.
Mouthpiece pops up, but not correctly (smoothly):
-Very slowly pops up (creeps up, takes 3-5 sec), something is clearly holding it back
-Sometimes incredibly jerky, sometimes will dislodge when it comes up.
-If it does eventually pop up, there is bad contact to a point where the Pax thinks the mouthpiece is completely dislodged and the temperature light will be on, even though the mouthpiece is actually still in the Pax, but popped up.
-If it comes up, jiggling the mouthpiece (but not dislodging it) ill cause the Pax to think it's disconnected and in temp change mode. This is really annoying because when I'm mid-hit if I press my lips in any direction, the mouthpiece will jiggle and contact will be lost.
Mouthpiece shoots out of Pax
-Quite literally, it'll just fly right off the Pax into the air. No, I'm not trying to make it do it like I did in 6th grade with ball point pens and their springs.
