I completely agree with what philipma1957 said. I also took a refund. I can only say that I was almost crucified on GPUHoarder Discord (by all the people posting) when I kept asking to see SQRL Miner and test it before Acorn was released.
You were "almost crucified" not because you asked, but because you never stopped asking at least daily, along with a dozen (or more) others, sometimes only a few messages above yours. Then you kept asking after you requested and received a refund. After a while it gets old.
Perhaps if others insisted to see SQRL miner and it had been released, we would have known earlier about the problems. It is still not out. I am surprised that you think that it is normal.
On another note (although related), have you seen this video?
https://www.youtube.com/watch?v=GNy5Ta5ccNg&t=1sNever said that I thought it was normal, but for me it was not unexpected given the nature of the project. I bought into the project knowing full well that it might fail. It was a way to dip my toes into the FPGA world for far less than the available FPGA cards available at the time.
I haven't seen that video.
