My duosida 16A works 100% of the time I've plugged it in 6 times
@irv - in regards to your question "compliance issues and design flaws" being real, I have read that the pin clamping force was too high and causing difficulty removing the plug. One case of the 14-50 plug being wired incorrectly. The thread is here viewtopic.php?f=26&t=22692

I'm not certain about the 'made by companies with little understanding of standards, safety and reliability'. I know that there was a risk when I ordered it ( direct from China ) and also each time I use it. The US re-sellers may test/do additional quality control and provide support, but I think I can handle it.
