Tbh I joined the room ready to purchase 1-2 pieces.
Ruplik can confirm because he knows me , and there was one more friend there.
If I get banned/kicked without any notice for saying "sons" , imagine if the miner stops working or some warranty problems appears and I wont call them sirs.
I was dissapointed by that behaviour.
Ruplik made a discord room with me and the seller and he did answer all my questions regarding warranty , shipping time etc.
Also it seems the shipping cost is $200 / unit.
