First of all: Hi to everybody , I'm David from Italy.
I would like to explain to you my experience with Bitmine.

Yes, in November (my order is #3102 for a full Desk) I have been in Swiss, that is quiet near to my town, to visit Bitmine and to meet the staff. As we had to pay them in advance we wanted to know diretcly whom we were going to pay.
I have to tell the truth and what I saw is this:
- Little front office a few peopole as staff (I saw 4 guys), but everyone really busy.
- A guy of the staff brought me and my friend to see the prototype and explained us all the problem they had in the past with the Avalon chip affair
- We talked about data sheet, software, everything
- We have been there for 2 - 2 hours and an half
- We had a pair of coffee
- We had a good impression and so we decided to pay them cash for the order

So, yes Bitmin exist it is a little office at the 2nd floor of a business building and yes they seemed to us to be honest and reliable.
However we should have to receive our Desk the first week of February, but... nothing. So I decided to send them an email and this is the answear I received:
(I wrote them in Italy as they speek Italian too, but the answered me in English and German):

That's a pre-typed email.
What do I think? I think that at the moment ROI is gone... but there is not only BTC to mine out there, there are other cryptocoins and now there are for me and my friend only two ways:
- wait the 61st day to claim our money back
- wait to receive the Desk and start mining BTC or something else to convert in a second time in BTC
Am I angry? No I'm "only" disappointed for all the time lost and the Btc not mined.
And Yes I'm disappointed too that someone could have made a Sting to two Italian guy  
But I think that at the end there is not a really sting but only a really bad business plan and failing organization in the Bitmine Company.

That's all folks, and sorry for my English.
Dave
