FYI you should be mining 1500-2k satoshis a day per unit. Keep in mind it takes at least 24 hours for your pool hashrate to stabilize and be able to show you how much BTC your earning accurately. And yes those 1-2k satoshis will have been more than worth your time in hindsight.
Stack those sats.
If they were mining as expected then I would have no reason to be disappointed. They just aren't. I can accept that maybe the issue is that these don't play well with Nicehash, although someone stated they did. I am not having that experience. Until I take the time to set them up on a different pool I guess I really shouldn't comment any further. I will say that I've been in the community for several years longer than you, and have mined with just about every miner that has existed since the FPGA days (I was one of the first customers to ever mine with an ASIC), but I do appreciate your urge that I stack sats... I also do respect what you've built. I couldn't have done it. I just wish I was getting more than 50% of the expected hashrate.
I know, and its quite an honor you purchased some of our units! I still remember some 400 dollars worth of PSUs you had helped escrow for 2BTC back in the day haha...those turned out to be some expensive PSUs
