MAny thanks for your answers, I'am sutisfied with them. I hope you did not misunderstund my post as a warning to stay away off your site. Just an opposite, wanted to get some clearification as a potential buyer. MY biggest concern aside of not getting the miner at all, is to get something not as advertised and then how to prove it.
There should be a way of you being able to confirm both seller and the buyer, tehnology would make it posible. Seller record boxing and buyer unboxing is also posibillity.
Any idea I have will share by pm.
Wish you best in this service

p.s.
Sorry for my English too
