From 100 machine, I got 3 defective miner like I explained above and already send email to them and got no reply at all.
and
106 power supply, I got 8 defective (They said they are going to replace it, we'll see about that whether I will received the replacement or not, will update if I received replacement)
So I guess if they didn't replace my miner, then that's mean the Avalon miner cost, I have to add up 3% (defective rate)
Avalon 6 all good no defective, just the some miner hashrate is not like it was advertise (3.5 Th/s) but at least no defective.
we'll see about the new type later, hopefully its not as bad as 741 like Philip mentioned and what I received.
Its interesting you say that. From 100 machines, I also got 3 defective miners. So there are now 2 of us with a 3% defect rate. Did you try sending an email to Steve? I'm sure he can help you out man. From the 60 PSUs that I have, I haven't gotten a dead one yet (fingers crossed). Compared to the antminers ( I have 42 L3+ and 50 S9s with 14 more on the way) Avalons are way more reliable. I lost 8 hashboards on the s9s in the first 3 days of mining and 15 L3+ boards, In total I think Bitmain machines have a 10-15% fail rate. Lets see who will send me back the quickest RMA. (my money is still on Canaan). I will detail my experience in the other thread
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.
So far, while there have been some major delays, for the 3 issues I've had on all machines which were all from direct Canaan orders, they have resolved them within a month.
If you haven't already be sure to have a ticket in with Canaan.

S9s on the other hand, almost half have a bad board now spread across many batches, all almost magically after the warranty period.
Though the price I paid and efficiency, it's still not terrible in comparison.
I do like Canaan's warranty more.
