The seller have displayed the circuit boards, they are identical to mine, which is working well. Compare it to "devildante" post and you can see it has quality components as well.
The only thing is that it is missing the 10K resistor, like mine as well (I have pointed it out in a post), but it works well without it any way, and I have soldiered a 10K resistor, it is still working and I cannot see a difference...
I bought mine last year for 56 Euro from AliExpress, I think from this shop:

But you will notice that they are not mentioning it is Full chip and not showing a picture of the circuit board..
Hence, I think it is better to order from the other seller..
