1.35 is still my top offer. In the end, it's still a used miner and 1.35 more than most of the other used prismas sold for. AM would pay for your shipping on the return which I am covering by sending a label. At least one of the boards are likely a gen 1 or 1.1 which are known to have issues then I am back in the same boat as you trying to get a replacement or refund with the added difficulty of not having purchased directly from CG or Canary.
