i ordered 4  innosilicon a4+ on the 13 dec 2017 and still no email whatsoever from them although i send them all the details ( payment, address )
does anybody have experience, ideas on dealing with them?

I think they are not scammers, but they definitely bite much much more than they can chew.
They make tons of money but they don't employ more people in their marketing department to improve communication with customers etc.
Waiting for email answer for 2,3,4 weeks is embarrassing and stupid.
They will definitely loose customers for this.

Innosilicon, the world renowned creator of the 28nm A2 Terminator, the most successful LTC miner with over 60% market share, is announcing today the availability of the next generation 14nm ASIC code-named A4 Dominator. This is a full custom design with a tremendous focus on efficiency, providing an incredible 1.2W/Mhs in a DCDC less daisy chain configuration. Available as both an ASIC and a complete miner, nothing can touch the A4 Dominator, and it is going to stay that way for quite some time to come!

A4 Dominator ASIC & Miner Specifications:

• A4 ASIC: 3Mhs per chip at 3.6W nominal, support DCDC less PCB
• Extreme Low Power: daisy chained ASIC running at 0.7V, only in 14nm
• Miner Performance: 600Mhs from 720W at the Wall or 850Mhs from 1020W
• PSU Requirements: common PCI-E 8Pins/6+2Pins with 12V output
• Included: Raspberry Pi running the most user friendly A2 terminator Software

Since the A4 Dominator is designed & taped-out in the worlds most advanced 14nm process, with 60% greater efficiency over any 28nm node, and our initial MPW chip/miner will be available soon, we are now entering the next round of full mask mass production with trusted partners. This provides an incredible opportunity to win in this huge market, for the foreseeable future, with zero risk. We also have production partners lined up for this A4 ASIC if you are looking for the finished miners. 14nm provides the pinnacle in LTC miner efficiency, with no better technology supplanting it in the foreseeable future.

Good news for this partnership round: we have opened our A4 ASIC/Miner production to committed partners in order to share in both the cost and the profit. Anyone who commits $1.5 million to this partnership will get to share our ASIC production masks or purchase miners “at cost” for your mining farms. We have fully de-risked the design by shouldering all the R&D and MPW costs for the testchips. Also, we will showcase our testchip and test miners in couple of months to demonstrate the A4’s unsurpassable efficiency. We need only 4 to 5 partners to participate in this incredible risk free win-win partnership round. This is the best ever opportunity to secure the world’s most profitable mining ASIC/Machines for the years to come. Further details will be available in the, limited member, partnership meeting. For parties with genuine interest, please email us today at sales@innosilicon.com or Skype at: Inno.miner.


Thank you all for your support and attention. A4 belongs to all of you. After the A4 Dominator comes out, we will offer a A2 Terminator and Farmboy miner replacement program so that our loyal customers can continue to benefit. The A4 Dominator will continue the A2 Terminator legacy in serving our mining community!

Thank you.
