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.
You're right Steve..I have some of those ones as well...
What made me post this is exactly what you are saying Matt. I have used these supplies before, have a basic understanding of how they work and the conventional way in which the terminals are wired.
I caught myself thinking as I opened this one, why are there 2 teminals for the live feed? It was confusing. Then I peered under the board to see if those terminals aligned to a common track. Obviously they didn't . So I took a step back.. looked more closely at the label and realised what was going on.
So for me, with a bit of experience, problem averted (even though I misinterpreted the positions in the first instance.) But it caused me to wonder, what If I didn't have that experience? I don't call it 'knowing what I am doing' - its just experience and a hard won eye for some potential troubles...
Perhaps you are right - its not unexpected for anyone assembling this that doesn't understand the potential implications of wiring it incorrectly to not pay attention to the line up of the sticker. But its a QA failure nontheless. The assembly has not yet evolved on this product to mistake-proof a fairly important alignment.
Another interesting angle - if the sticker had been placed on the side of the box it would be much less open to misinterpretation. By placing it where I would expect to see aligned terminal markers the manufacturer has inadvertently increased the likelihood that I'll do something silly.
The biggest risk on this type of gear (and a lot of the cheap gear we buy) is that they get it half right... and we assume the rest!
