A very high quality unit with elegant control software. Widely thought to be among the best miners made. One of our staff runs these devices and on 110 volts has observed power usage as low a .75watts per GH/s. Which even today is near state of the art. Operating on 220 volt will maximize performance with of course a bit more power usage. You choose. Call with questions. Shipping included in the lower 48 States power cord not included.
