Love the information posted based on personal experience. Great idea to post in this format. However, try to keep your "opinions" out of it or you will destroy the good this thread could bring. Facts only and check your emotions at the door.
I disagree. One's opinions on a company can't help but color one's review of a mfg.. These opinions aren't formed in a vacuum but come from our accumulated knowledge of a manufacturers actions, plans, and public behavior.
For example: my opinion is that AMT and BFL offer awful customer service. This very well plays into my own decision making process when community fund raising hundreds of BTC on the behalf of trusting miners that join our co-op.
No offense but trying to discount or to not include our opinions on an ASIC mfg. review thread sounds protective of one or more of these mfgs.
Edit: HashFast is at the bottom, because that's my opinion of them changing TOS for Batch 1 and 2. Partial BTC refunds from them aren't going to cut it.
+1 it is all about the PERSONAL experience.
Here is how I see it. If you mess up and fix the problem then you are deserving of further trust think BuzzDave. If you mess up and do not fix the problem think Avalon / BFL / HashFast then you are undeserving of further trust.
Personal opinion matters as time passes and more opinions are collected you can see a much more clear picture of what is going on. If there are significant numbers of complaints and little or no resolution that speaks volumes. Whether or not people are polite or vitriolic in their complaints matters as little as does the patterns that develop. Can you really determine whether the company is good or bad based on a limited number of personal opinions? I think there is value in it if the experiences are first hand.
Avalon chip buy. I personally went through way too much drama and the excuses presented by Yifu and the lack of any proper communication for well over 9 weeks was more than enough for me and the members of a group that had raised 80,000 USD to buy chips to put me off EVER buying Avalon anything again. I would as others agree they are NOT nor should they ever be trusted again regardless of their ability to ship Batch 1.
BitFury chip buy. Was involved in a small order it was shipped on time without delays from Megapower BitFury USA.
BitMine.ch A1 chip buy. Involved in ongoing project getting 2 sample chips for the prototype we are building based on the fact we provided some support on the designs of the chip. 3 week delay there abouts as indicated by BitMine.ch. Has not adversely affected our prototype development. Fairly responsive team but they need to make sure they have a CRM system in place to handle potential issues with a very complex ASIC design.
Black Arrow Minion chip buy. Supported some of the documentation for the Minion we are currently waiting on some samples / full order when the chip fabrication gets done. No warning flags so far. Very responsive team that will need a much more robust CRM system as they were slightly caught out when they had a larger order volume swamp them. They seem to be delegating some of this work but we will see how this progresses.
That is the end of my list.
Now moving forward this should be STICKIED! This has to be the go to post for us in the community to guide and inform.
[Edit] Entropy-uc yes agree 100% with that
