PureVapr is right.
@TRVB
I am an electrical engineer for my past trade and currently work as a scientist (yes, doing actual research funded by the government).
I am sorry to say this, but with the utmost respect. I have owned 3 different black PonGs now. Weighed them, they are definitely the new PES piece. Melting, cracking, flaking bits of plastic abound. I have had one flavoured mouthtip and one non flavoured mouthtip melt as well, into the mouthpiece adapter. I have only owned my PNP for a fortnight now. You claimed your 'scientific opinion'. Well, it so happens that I teach the scientific method at universities for a living, alongside my research.
The scientific method entails first of all, the accurate description of replicable observations. Observations described in this thread would lead to several points:
1: The plastic on each of the PonGs you guys have designed can melt, flake and chip, this has been replicated by many owners of the PNP, including myself, many board members and a friend who does not post of this board and owns a PNP. I appreciate that the plastics you have used have been rated for certain temperatures above what the PNP is supposed to produce. However, this does not change the fact that swathes of us have damaged mouthpieces within a week or two with a new product. Having been in charge of warranty/service/repairs for several companies in different industries: this is a significant problem. Your customers, at least on this message board, are being pretty cool for the most part about this. They appreciate testing of new products can take time - the least you guys can do is acknowledge the genuine problems that we, your customers have encountered. I love that you guys have been quick to develop a solution, but we haven't heard about availability yet!
2: The battery needs to be replaceable with a new battery able to be sent out to users. Sending a product to the other side of the world (at least in my case) for battery replacement is not helpful for something that many of us rely on every day. Again, with the utmost respect, you guys should have prepared for this up front. Batteries by their very nature have a use by date.
3: The PNP is otherwise close to a masterpiece of design, hampered by these issues.
In a burgeoning industry such as yours, address the first two issues in a way which satisfies your customers, and let me assure you, you will have a product which is head and shoulders above the competition in portable vapes. The size and discreteness of your unit is fantastic.
I also echo the above call for a black glass GonG adapter for stealthiness, if possible, that would be lovely! Please, do not take my comments as anything but constructive criticism, but please, take your customers seriously and don't invalidate them by standing by a product that plainly has an issue.
Even if you couldn't replicate the issue in your testing, it remains that many of us have, and by standing by your view in the face of this evidence replicated worldwide is either saying we are being dishonest, or just ignoring what we say.
