Thank you all for your input. I assure you i would not abuse this guarantee. This is the first time i have ever experienced an issue like this and i was freaking out that this guy could have just walked off with all of my money.

I just can't believe that people are willing to lie, cheat and steal like this. I certainly hope he gets hit with a big dose of Karma!

(Modertors: So sorry if I posted this in the wrong forum, i wasn't sure where this type of thing should go and I realy wanted to get some feedback from knowledgeable folks. So sorry if i got it in the wrong spot.)

I recently purchased an Antminer S7 on eBay from what appeared to a reputable seller with thousands of positive reviews.

HOWEVER, everything did not arrive as described... Here are the details... Has anyone had any experience with purchasing these types of items on eBay? What are the chances ebay will make things right with buyer protection if this guy tries to screw me?

The description had many positive things to say but some of the highlights were...
“Used Antminer S7 in « A » WORKING condition! and in « B » Looking condition HAVE small scratches and dust but does NOT affect performance of the miner.This was pulled from a rack of equipment mining at full hashrate. Sold as-is, no warranty, no returns.”

Also at the bottom this was said:
Warranty and Returns
There is no warranty on miners/psu as those are used. Asap you receive the miner, please test it and confirm us its working. If you don’t confirm us after 72h that miner is working we’ll consider all is good
No Returns are accepted.

Long story short... The miner arrived with a few problems...
1. One hashes at full rate. Yay!
2. One hashboard was dead on arrival. (when this one is run with the working one, the whole unit only gets ~6 gh/s instead of the 1500gh/s it gets with just the working board, is this normal?
3. One hashboard has a loose heatsink (I have not yet powered up this board so i don't know if it works or not). i didn't want to power it up out our courtesy for the seller just in case they have some way to repair it after it is exchanged. <- hopefully

I am understandably upset and seeking an exchange for a working unit or a refund. I have had some communication via eBay messages but he has not offered any reasonable suggestions to resolve the situation. All he has offered was a replacement fan to "fix" the "cooling and vibration" issue... I don't even know what he is talking about!!

He has since gone radio silent so I submitted for a return/exchange through the eBay process... any advice? HELP?!?!? I stand NO chance of a return on investment if 2/3 of my rig don't work! eeeeek!!
