I did get one of these units to review and the review is live now.
http://www.cryptocoinsnews.com/news/bittech-1-ths-bitcoin-miner-review/2014/04/24
It is a good miner. There are some issues but none that are different than any other Dragon I have seen.
The one blade that collider is having the high errors on seems to be not enough power. I think the more robust power supplies that Bit-Tech is working on getting in the newer batch systems will take care of that and allow for better over clocking.
I am looking forward to the improvements that Bit-Tech is working on.

Then your house caught fire..? 
Additionally, my unit will not start up when i position it like a desktop, but only when i put it down flat like a server. When i move it too much while it is on, it will simply shut down... What could that be?
I had the same issue with a GPU rig once. Turned out that the power cord didn't mate with the socket very well. I ended up tying the cord down to the rack the rig was on, then twisting the power cable before connecting it to the PSU to provide some rotational torque.
Yes, I have the same issue with my miner and the Dragon PI Image, nearly 30% HW errors on all four modules. 
Anyone knows how to check the running frequency of the miner with this version?

BTW...did you try a Technobit version of the software...? ...People are claiming that is quite stable...
What do you mean? custom raspbian linux with cgminer and hexminer patches?
Also i seem to have a problem with one of the boards:
That seems pretty bad... essentailly one board is nearly defective.
It seems i have spoken too soon.
While you could technically say it is working now, with the dragonminer firmware i am only getting 850GH/s.
This seems to be due to an unusually high number of hardware errors, about 17% at all but one board. This happens even thoguh my cooling is excellent, intake temperature is under 20°C.
Has anyone run into similar troubles? I set the difficulty to the correct one the pool was providing so i cant imagine any problems there.
Does anyone know wether the amps on the DC/DC is software controlled? It seems to me that a power draw of 1kw flat is a bit low for these chips clocking 31.25GH.
Maybe this can be fixed by using the correct firmware?
I am currently running on gh.io, has ayone had problems on this pool with this miner?

Contacts...I guess...Mechanically something is loose...unstable...and is loosing contact(s) when moving...Just my 2 cents...if you want to check...

If you do a "ps -aux" look for your cgminer and see what options it has. Maybe one of the A1PLL clocks is set to high.

Would like to get in on next batch.
Watching and waiting for the next batch 
this the next batch will have the newer upgrades correct?
Bit_Tech
Please provide tracking information for my order.
Thanks,

Yes, router etc. was setup correctly, i am sure of it.
I had connection to other devices on the ip-range too, and scanned the whole range just to be certain.
I also connected directly and again scanned the whole range, nothing.
Now i tried your image, however when i click on the stats page it gives me this:
This seems to be an error when the pool connection is not yet achieved.
I am now certain that all network settings are correct, as the device can ping any website without problem.
Edit: Its ALIVE! (muahaha) dont really know what i did to make it work though, it seems as though it will only take pool settings when you´re lucky
... atleast with the dragonminer firmware. Got a good 1th though, so thats nice.

ehehehe a good laugh here because of you, when you insert values on pool field you must wait about 5 to 10 minutes for it to start
Anyway him happy you managed to work that out
happy minning

Hey man is your router on the 192.168.0.xxx
If not you must connect miner directly to computer in order to find it
use this image for the miner
https://dl.dropboxusercontent.com/u/92967009/dragon_image.7z
use this program to insert image in sd
http://sourceforge.net/projects/win32diskimager/
This image is from ltek miners, but it works 100% on these miners, i´ve tried it myself
The ip should be 192.168.1.163 if i remember correctly

Can anyone share some insight on the setup?
I am truly desperate at this point.
I set up my router to the ip range 192.168.0.x, after having changed the adapter settings of my lan card to multiple other popular ranges and scanning the network, still no sign of the unit,
although i see the lan-port flickering on my router / switch that are connected to the device.
My device has the number 87 on the side, is this a hint to the static ip?
Any help would be appreciated. I already checked that the rasperry pi in the device is plugged in properly etc, i even put in another sd card and it started up fine.
I am not a newbie when it comes to setting up miners/networks but this one seems unreachable...
Edit:
I put the sdcard into another pi and connected it to a screen via hdmi. (I didn´t plug in the conncetion cable to the device)
It says it is unable to mount the partition, does that mean the OS is damaged and i need to get a new image from somewhere?

Go for 192.168.0.87
and voiláThanks, i already tried that (in fact that was the first thing i tried, both via web interface and ssh, no device reached.
Also, the first time i turned it on (without connection), the fans only turned gently.
Now the fans turn full throttle all the time, although it is not mining. In my opinion that is another hint for a damaged operating system? ---> no fan input---> fans go full throttle?
I also tried scanning the ip range 192.168.0.xx, no new devices there, router doesn´t show any new devices either.
Has anyone got a download link for the firmware so i can try on another sdcard? I really think the sdcard is damaged.

Im interested in that.
i will take 3 units once they avalaible.
To guys who received units can you provide info about quality etc?

Nice machines, similar to lketc dragons, 4 blades.
Hashing average to 950gh/s .
i will try to post pics tommorow.
ps. Here are pics from Xian01 https://bitcointalksearch.org/topic/m.6284148
