I know DF64 from me buying experience…
I know DF64 from me buying experience of the DF83V grinder. Their support was top notch. I got answers to all the questions I had before deciding on what grinder to buy. I chose the SSP Cast Lab Sweet espresso burrs, and they installed and aligned them free of charge, which I take as a great service. Delivery to my home in Denmark with FedEx was swift (6 days), and I had no trouble with customs, and no taxes were added on top of the amount All in all, I am very satisfied with DF64 and there service.
