Greetings!

I am just getting back in BTC and picked up two Terraminer IV units for $300 each. I really had no intention of starting mining again but the price was right and having Th/s just sounded cool. I managed to get the latest firmware, manuals, etc from the site, despite them taking it offline (thanks Google cache). I have not been able to find much recently on these and what I have found has not been too positive. I would have a different perspective had I purchased at retail when they came out but after seeing these I am impressed. Granted I only have old 60-110Ghs BFL hardware to compare but these seem solid. As soon as I got them I cracked the seals, cleaned them out and started to inventory the components. One was perfect and the other had a core that was not working. I was able to track that pretty easily to a pump that was not running and after a few minutes of highly technical, very sensitive, work with a specialized tool (removed pump and smacked it with the back of a screwdriver) it was once again pumping and all cores running. So I am currently hashing on Slush's pool and getting 3.2-3.6 Th/s between the two after 24 hours straight and overall I am pretty impressed with these units.

Does anyone have any experience or wisdom with these that you would care to share? How about pools? I used Slush's in the past, and I like the new beta site, but the luck has been bad since I joined the pool. Hopefully I don't have a curse on my miners.

TIA

The Cointerra units do run well so long as you keep them cooled on the different stepping settings. I had 1 of them and could only hash it around 1.4TH each due to over heating (stepping 5 iirc).
