I have tried to buy X6 since last summer, messages get through in this forum sometimes and e-mails are sometimes answered.

BUT I think chances are very slim that You get any miners with group buy or something.

Got some messages through now at December and I told that I can fly to Kiev and pick-up 2-3 kits and pay them and then buy more later after testing, I told also that I want to visit their office/factory.
Hotmine went silent after that so I think they don't have the product or at least don't want to sell them to anybody.
