OK, this is my review of the Hex16B and ordering from Technobit.

Shipping / Ordering
19th Nov 2013, 1x Hex16B + TP-Link Router, for December Batch 1, was delivered Dec 13th, Paid PayPal, Shipping DPD €32
22nd Nov 2013, 1x Hex16B, for December Batch 1, was delivered January 22nd, Paid BitPay, Shipping €4 "larger order"
23rd Nov 2013, 4x Hex16B, for December Batch 1, was delivered January 10th, Paid BitPay, Shipping €4 "larger order"
PayPal order arrived on time, BitPay orders were late. Suggest paying the extra 5% for PayPal to get order early.
Combined shipping for "larger orders" does not work, and may delay your order, suggest adding shipping to each order.
There was no tracking number but all arrived in the UK around 7 days after the ordering system went from "payment accepted" to "shipped".
The TP-Link router did not arrive pre-flashed, but it's not hard to do it yourself.
I suggest using one because it becomes a 2W mining PC. If you want to know how to set one up check my old posts here...

It's not a standalone device you have to set it up with a PC PSU by shorting the green and black wires on the motherboard connector.
My Hex16B is hooked up to a molex connector for power, unlike the first one on this page, which is wired into the yellow/black wires.
The 6x Hex16B I have + TP-Link (running at 540/900) are pulling 415W at the wall for 270GH/s return.
That's a very impressive 0.65GH/W or 1.54W/GH at the wall!
I'm using 2x Enermax NAXN 350W (2x 150W +12v rails) PSU because they split all the molex out to 3 separate wires and are cheap < £30/$40.
Beware of putting too many units on the same wire as it could melt the cable!
These PSU are only 83% efficient so that makes my Hex16B miners around 56.44W at the board.

The chips on my Hex16B are Bitfury clones they say "BioInfoBank" on them.
http://bioinfobank.com/I tracked the origin of these chips back to the BioInfoBank 100TH-mine project
https://picostocks.com/businessplan/19.pdfThen found out that
http://www.bitfury.org was in England! Nice work guys on making 55nm as efficient as KnCs 28nm!

I too have problems with power leaking out of the USB port. USB hubs with power/surge protection may refuse to work with some units!*
I have the molex versions and there is a resistor between the +12v and Ground, is this to stop 12v leaking out I wonder?
I just bunged the problem unit on a cheap $3 ebay hub without surge protection and it works okay.*
I'm using a cheap TP-Link router for mining, so it don't worry me, but I wouldn't risk connecting this to my PC/Laptop.
I'm happy with them, they're really well made, they are twice as efficient as the Avalon and BFL, but possibly there is a problem with Bitfury chip shortages at the moment and a miner that's not mining is just losing money, no matter how efficient it is.
* There's an update to my power leakage issue here later in this thread:
https://bitcointalk.org/index.php?topic=338790.msg4642613#msg4642613The other 5x Hex16B I got didn't leak power but the one that did caused issues when I tried to use 2x PSUs. This is how I solved it.
