Sorry to hear that Phil.
But Canaan also owes me around $150 since they did not fill and submit certificate of origin correctly.
But, I said what the heck. Money comes money goes.
the S7s (I have 14) are working very well and was considering the S9 once they were out.
But from what I have seen, I am not ready to pay $8000 for S9s or R4s.
And shifted that money for the A7s.
If the T9 is going to be okey, I will go for it since I have sufficient funds otherwise again further A7s to purchase.
I hope you will be refunded. Just drop them emails and follow up.
