If shipping broken units back is not working out, it might make more sense to see if there is a trusted member here who could do the repairs nearby (same country would be good). This is what was done with Drillbit boards that needed some repairs. Drillbit paid for the repairs in that case. I don't know if BTMine will offer to do this but it would go a long way in terms of building some trust back.

id prefer not to waste any more time with this junk and invalidate my paypal claim. the way btmine chooses to communicate also fills me with no confidence of this ever working out.

I don't know how everyone's came, but mine wasn't even repairable. One of the units was completely unsecured and had broken part of the PCB in shipping...So I can't just desolder and solder something back on.

Soo....what's the recourse for people who don't want to pay $400 to ship something back and then have it refused to be signed for?

Great idea, I would be glad to list this on my wiki for anyone willing to do for a fee or as "warranty" work if BTmine agrees. If no one is interested, I would be as a former RF Engineer. It would be great if we had several people who could offer this service.

These Chinese units will soon be flooding the market and sadly, I do not believe our experience will be unique. That's is why I created the wiki.

If it is the factory power supplies like mine, they are getting weak on output. I reduce my frequency to 1300 and this seems to solve the problem. I am giving up a little speed, but gaining over all. I am about to order some new upgraded power supplies!

I've managed to get both of my units hashing at 200Gh/s+, however occasionally the hash rate will drop to 35-40Gh/s without warning with very high HW error rate. A reboot fixes the problem, but I'm forced to reboot the machines 2-3 times a day (and lose valuable mining time!). This happens on both miners.

Any thoughts?

Interesting - I've been running at 1500Mhz using 2 Corsair CX750s per box. If the hash rate drops keep occurring, I may try to take it down to 1400Mhz. Thanks!

What firmware are you using?
If the latest firmware doesnt solve it use crontab to restart cgminer automatically.

In System -> Schedule Tasks

Copy and paste to last line

0 */4 * * * /etc/init.d/cgminer restart
0 20 * * * /sbin/reboot

This will restart cgminer every 4hr and reboot miner every 20hr.

Sorry to hear this, I hope you get your refund, it will cost a lot to ship them back. What happened to them, what kind of damages?

All 3 miners received, all 3 broken beyond repair. Asked for money to be refunded on paypal. We'll see what happens.

I'm not sure the address will fly to ship back, i asked the seller to confirm this. Also stated I want money to ship back.

I filed a claim with paypal that is now in my favor.

Cords cut, capacitors broke off, tplinks busted, cases bent, etc.. 2 of them nothing inside was connected to the case. 3rd was ok, but broken parts.

I am on the same boat as you regarding paypal. I shipped them back the broken parts for repair and they still haven't accepted delivery.

How much did shipping cost? I'm waiting to hear from paypal on shipping back. I'll let them know that they aren't taking delivery.

Its $378 to ship the hunk of junk from SoCal back to china.

and $118 to send a small 3lb box which they still haven't accepted delivery of.

BTmine asked me to ship back the boards that where defective and they are MIA at there location even do they knew my stuff was arriving this week.

also have mine boxed ready to go back but hesitant to spend 300+ on freight if they arent signing for it. paypal says they need a signature for goods valued over 250 to refund.

What's the option for a refund if we can't ship it back? (they aren't accepting them...?)

When you opened the case to paypal, did you link to the first page of this for the product page?

Just thought I'd post some good news in this thread. I received one miner yesterday. Both of the Avalon boards were loose and jumping around in the case but amazingly nothing was broken. there was a pile of screws and a few transistors in the bottom of the case as well (which apparently must have been from another machine. One of the Avalon boards wasn't hooked up. Once both boards were attached I was able to mine at full speed (averaging around 200gh/s on the guild site)
