A quick update:
6 weeks after, I still received no module from @sugarfreedaddy
he replies to messenger messages.
he said that he will refund me "asap" but that he currently does not have the money. I don't believe him whatever he says :D
He said that he is not home and can't ship (but he keeps on posting new ads here and on ebay for you people to buy :D )
For several reasons:
6 weeks no module received
he refuses to communicate his name or adress
he ships modules from Poland but his ads claim that he is in Germany
when he ships, he does not communicate his own name and no phone on the parcel... he ships without name...
For all those reasons I believe that he is a real scam and as such, I really want to state it clearly, hoping to help modulargrid people: this guy is here to scam.
No drama please.
Happy patching everyone :D
