I hope you can appreciate pre-orders are frowned upon by this community, and you are going to come under intense scrutiny without providing proof of product existence and performance.
Yes. I understand and appreciate this. It's actually giving me personally even more energy to complete project in given deadline and within all specs.
At the same time, however, do not agree on the language and the way some of comments.
Ia I said before we are working on this project for almost 6 moths. This is DESIGN. I dont know will you understand this, but designer need to put some data while designing. SOME EXAMPLE DATA. Are you really so stupid?
Graphical explanation for all malcontents.
Forgive me for being so forward, but given that I have already explained you are likely to come under intense scrutiny for a pre-order scheme in today's marketplace, and your acerbic replies to pointed queries (... that type of abrasive attitude with potential customers generally does not lead to profitable ventures launched from these forums ...) I would suggest you go radio silent and not make any further posts until you have a working product and something that trusted members of these forums can verify.
I would look to Spondoolies or Bitmain as setting the standard for launching new products on these forums.
Anything else is folly in todays marketplace.
