Compared to other miners....Yes. It is rather high, but they perform very well from what I've seen.
I just ordered 2 of the M3's about a week ago. It will not kill me on electricity, but I'd like it to be lower.
I'm hoping that eventually, someone with the skill can "jailbreak" the program to give access to the
voltages. Turning them down just a notch could really help.

So....if you don't pay a lot of electricity, these are still a good option.


Edit: They will be taking orders on 12/20/17 for Current, Feb and March stock.
