Yeah, I had prettymuch the same results with the ten I bought through Aliexpress. Two of them were
misaligned and 3 were fairly weak. None of them even came close to my DX true 5 which still is only
63mW. I suspect they use a weaker diode or are underdriven, maybe a combination of the two. They
didn't come in the black case either, just separate little bubble wrap bags. The five good ones are still for
sale if anyone wants one to play with.
