You think a high pitched scratching noise like nails on a chalkboard, and zero resistance to corroding almost instantly does not affect performance?
Does it not also give you health concerns? It's not exactly acting like decent quality SS is it? Mine will be almost certainly be going in the bin if it ever gets here.
of course I do have concerns. I may just use the og cap for now until some explanation comes. I did a little google research on metal whine during induction and this comes up (it's more about/for induction stoves, which I don't use.. natural gas here):
Magnetostriction:
Induction heating uses electromagnetic fields to generate heat directly within the cookware. Some metals, particularly those with a higher degree of ferromagnetism, are magnetostrictive, meaning they expand and contract in response to the magnetic field. This expansion and contraction creates vibrations, resulting in the audible whine or buzz.
And AI says..
A high-pitched whining or buzzing sound during induction heating is often a result of magnetostriction, a phenomenon where the magnetic field interacts with the metal, causing it to vibrate. This vibration is more noticeable on higher heat settings or with certain types of cookware, especially if the cookware's base has different material layers that vibrate when heated.
edit: also says happens more often on lower quality cookware so yeah a different quality of stainless may have been used. as far as health concerns from it, unknown
edit 2: no doctor would approve even the highest quality metal as safe if you think about it.. i mean we're inhaling heat off hot metal, lol. it's a matter of how much risk you are willing to take vs. regular combustion.. not sure if anyone will truely say it's all safe.. even if using a venty.. i don't take the cap as hot as others do and the higher the heat the more risk of off gassing (logic) but really the jury is still out on safety for all vaping in general.. my gut tells me something like the terpsicle would be the safest with indirect heat and all glass..but not as mobile/practical on the go (i dont own one)
