I hope that people appreciate that my comments here are very specific, not self-sealing and do explain how my concerns might be addressed. None of this is intended as general ad hominem attacks.
I don't know these guys personally and who they are personally is not relevant here, I am speaking about the products and their designs specifically. Upon reflection, I wish no ill-will to TVB, but I do believe genuine concerns need to be addressed.
@TherealVaporblunt I appreciate that these kinds of technical questions must be directed to engineers/scientists and most likely the former, since they are more industry friendly with their lingo and affordable for the purpose. However, these engineers really need to substantiate why they think these are acceptable materials. They also need to be shown the pictures of all the melted pongs just so they don't just argue to avoid having to admit an oversight.
Noone likes to be wrong, but it is important on these kinds of things that we get it right if we find problems, quickly. Please do not use PES in your airpath in any future products, hell, see if you can get it out of the Baker units in a practical, phased introduction that won't send you guys broke. PES is perfectly cool (pun intended) outside of the airpath though. Still, be judicious, don't use PES to support the mass of heavier connecting parts (for instance holding a gong onto a vape, connecting the pong/pgong/interim gong to the pnp main assembly, etc) or anywhere that might get warm from use. A sturdy vaporizer is a good vaporizer, inside and outside of the airpath! Any customer will tell you this.
I would like to make polite recommendations to make your products safer. We all just want some honest good faith and due diligence carried out in terms of the sourcing and selection of your materials, especially in the air path. Appropriately glazed ceramic, titanium (preferably gr2 or purer), stainless steel, glass and myriad other materials are safe and delicious when used in air paths.
Sourcing these materials right now for prototypes myself, I know that plenty of these materials can be sourced at reasonable prices and your customers will hugely appreciate the benefits to taste as well as the peace of mind with regard to safety.
I must clarify, I am not a competitor, I do not have any commercial ambitions for my vaporizer at this stage or in the future. My scientific work takes precedent.
I only offer these suggestions to try and turn around what I see as a series of very problematic design decisions. Despite my jadedness with TVB, I have never been able to deny that the bullet design and the PNWT are great concepts/products. This has just made me wish the rest of your designs were on par.
Hope you understand that there is no need to take these comments personally, I also apologise for getting too irate if anyone feels I have. Really we should keep it to the issues.
Hopefully this is a reasonably clear post, I have just woken up lol
