I guess the replacement and warranty thing is just BS and sweet talk. I have been asking them 2 more times and what I get is just silent.............
until I got replacement, I guess the 90 days warranty, for me is just a typo by them, it should be no warranty.
I'm just wondering have you contacted anyone at Canaan? I'm not sure what you mean by asking them 2 times, how was this done? The process for defective units is pretty straightforward and can take a few days to hear back, but you have to at least open a ticket; was this done? Also a while back one of their representatives Steven had been talking with the group and provided us with his email. You probably dealt with him when you bought your 100 unit order, he tends to have something to do with larger orders. His email is
Steve@canaan.io .
So far from what I can tell is anyone who has had issues with defective equipment, has had their issues resolved, if they take the proper steps. Good luck.
I have 2 deffective 741 (one hash board dead on each one). Opened a ticket, support said "deffective PMU, will replace". The order for 2 x PMU was created 2 weeks ago. (received on email).
Since then, nothing. No tracking number, no package on my door, no answer from Caanan..
Will keep waiting for a few days. If not, I will talk to my bank to open a refund (paid them with my CC on minerwarez).
