As pangolinminer promised to ship out before 31 august 2019, in fact they dint do it , during august 31-sep 15 pangolinminer still selling instant stock which is usd 4000, that mean they purposely dragged pre order customer stock and selling it for higher price to make profit , they thought microbt have enough stock to supply but guess what,  they were wrong . This issue happen because of pangolinminer greedy , they wanted to earn more but sacrifice our pre order customer profit . Now they are just keep silent , without answering any email . what a coward.

We can say 100% before August 31. But unpredictable for 20th.
( Sorry I dont no how to post screen shot if anyone can teach plz)

This is how pangolinminer promise me before buying !!!
After that they keep selling instant stock which is usd 4000 and dragged my order, now they said manufacturer microbt have problem with the delay of chipset delayed for 3 weeks. If they ship it out before august 31, I think our as pre order customer already mining.
Pangolinminer also wont pay any compensation for the delay, they are like cheater , fxcking liar, company like bitmain wont have such issue, only small company wont care about their reputation will do it.

NEVER BUY FROM PANGOLINMINER ANYMORE!!
they keep selling m20s for instant buyer with Usd4000 but dragging pre order customer stocks, if anyone ask in telegram about the issue, pangolinminer will delete the question and ban the user, that's why nobody complaint in telegram group, now August batch stock nobody receiving yet, if asking no1 will reply , this is how pangolinminer work.
