Funny that I am replying to my own message, but I wanted to add my photo of my 2nd issue regarding discoloration. There is definitely discoloration from use. Plus this is much more today than yesterday.
Yesterday, that white area was half the size as it is now. That is not dirt or buildup. The top edge which is flush with the mouthpiece is rough and jagged if looked at very closely. Others might think health concerns, but I probably ingest or breath in worse stuff on a daily basis. I have not even had this for a week yet but am thinking about long term reliability & aesthetics. I do NOT want to walk around with a funky looking PN Pro and when asked wtf that is, I do not want to say negative things about white discoloration issues.
Regarding @
grokit and the sidewalls:
The above is a PonG that has a THIN wall.
The regular mouthpiece has a THICK wall and a recessed screen.
@
Engineering my PonG weighs 5.31 grams with screen.
I will also contact TRVB about a replacement PonG. TY
add: one bullet weighs 1.38 and the other 1.24
