agreed. Most of the miners I bought from bitmain were s3+, way back , and I think I had only 1 fail. I owned 1 s4 and had a power supply go out. Replaced it, and it was fine after that. So most likely its their higher end asics that get very hot that are having issues. Today I own titan miners, and it doesnt get more flaky than those ... LOL So, Ill wait for the L3 to come out and see what people say about them. The L3 is MUCH more efficient than titans, and they have to be more stable, but then anything is more stable than Titans..LOL
Its sad that bitmain wont honor their warranty, because I feel like they could be the best asic company out there if they did. People understand that machines fail, its how the company handles it, that makes the difference. Too bad Zeus didnt continue with their scrypt miners. I have 9 of them, and I never had even 1 problem with them.
I dont follow the S9 or S7s. Is the failure rate high?
I even overclocked the S3's to max, and ran them 24/7 and they were great. But, they were only .5 TH/s each, and drew 600W.
I think the best strategy for the L3 is NOT to buy until atleast batch 3 or 4. This way the price has come down, and youll have a pretty good idea on the failure rate also.

Reports in the other threads on the S9 and R4's have a failure rate in the 10-20% range. BitmainWarranty is a consignee and not part of Bitmain so having repairs done through them in the US will cost you and are not really part of the Bitmain official warranty. Warranty work has to go back to China. It is a long ongoing story on the S9 thread.
It is this current Bitmain history that is worrying about the L3. The S9's are still shipping new batches and people are still seeing failures. I forget what the last batch number is for the S9, but it is in the 20's and still having problems.
