> Missing insulation tape.

Yeah, wow, how does that even happen?

Oh well that's not very typical, I'd like to make that point... (reference: https://youtu.be/3m5qxZm_JqM)

Seriously, these findings are facepalm-worthy. It really doesn't inspire any confidence in their quality control.

It looks like, based on the infographic, the insulation tape was punctured by overly tall welds.

That is not the missing insulation the parent comment is talking about. The insulation puncture is another fault.
