Of course the Chinese factory would argue this is not a Quality issue. the Label is correct nor the terminals are not marked in wrong order, (otherwise you would have complain you don't have a LED screwdriver).
I agree the label could be beter positioned, but to those people who don't use them, nor have any idea what the silver boxes do, they think they have done a good job.
As always if you don't know what you are doing, don't!
BTW. Training illiterate ppl to do complicated tasks using drawings can result in amazing concepts. My parents have worked with illiterate ppl in PNG. they showed what an illistrator thought was a simple drawing with moderate perspective. after a long discussion about the content, it became very evident a main blocker to learning was the class trying to understand how the machine (TV) made the ppl so small compare to a Pineapple sitting on the TV set.
