The H40 V2 hand grinder is fantastic. It is extremely well built and very precise. It punches well above its weight at the current price. It performed perfectly and help me dial in the grind on several different beans for my espresso machine. I do not use it every day, as I have a 64mm flat burr grinder as well. It is great for full bodied medium-dark roasts. Even when I am not using it to grind, the bottom piece functions perfect as a blind shaker. I grind directly into it, then place it on top of portafilter and distribute. It is very multipurpose! It would be awesome it they sold a magnetic lid for the bottom piece so it could be a true blind shaker.
