My purple Pax arrived from Vapeworld yesterday, and I've really been enjoying this portable. I've used the MFLB with pleasure for years, but the Pax will be my go-to portable now. The only problem is, three loads into using the Pax, the mouthpiece has become very tricky to close.
I saw earlier in the thread that BryE23 was having similar issues, but not sure that a solution was ever found (re-read the thread from page 49, where BryE23's post about the mouthpiece appears, but didn't see anything or missed it). I'm able to get the mouthpiece to stay closed only by being very slow and deliberate in my motions. I need to press it all the way down very gently, then very slowly let up pressure until it catches. Even then, it often won't catch. I have to move much slower and more deliberately to get it to catch than the demonstrators in the official videos from Ploom, which is why I think something may be off with my device.
I've cleaned the device to make sure there was nothing sticky or clogged, even though it had only been used three times. It works great otherwise, but I'm still going to contact Vapeworld and see if I can get a replacement unit. I'm worried this will only get worse with time, and it's just not good enough for the price of the vape. But since there are only a couple of us who have had this problem (or at least reporting it in this thread), I'm guessing it's just a faulty unit.
Other than that bit of annoyance, first impressions are fantastic. And thanks to everyone for taking the time to post such great information.
