This is a total nitpick on my part but i suspect you meant to say something like “burden of quality”. It’s incumbent upon a manufacturer to produce quality products (safe to use and perform to advertised claims) based on a reasonable person’s standard of what quality means, if quality is not somehow empirically definable (in this case it is - blueprint vs actual unit).
If a newly purchased item’s defect is visible to the naked eye, I’d send it back.
I wonder if the OP
@Boss334OP has heard back from the manufacturer yet…
