Haven't taken the module out of one yet but they appear to be just like a zillion other ones out there. 6 units purchased and only one hit over 80mw (the rest were under 40) and they have well over 50% IR)
Conclusion is waste of money.
Ebay seller "overfeel" are much better out of N.Y.
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.
