Very good burr grinder with very functional adjustments. Holds the perfect amount in 1 go for my pour over setup. My only critique is that is has 3 unconnected hopper sections that are quite small and hard to hit. I have to be very careful to not spill and one can fill before the other 2 causing some difficulties closing the crank, but it just takes some self adjustments to get around. Overall I'm very pleased with it for the price.

Great Quality, Great Price.

Color: Black

I have used this for a few days now and it works great. It is very well made and has a large range of adjustability. It is quite small and easy to store. Definitely worth the money.

Nice Grinder at a Great Price

Color: Black

I bought this to use primarily as a travel grinder and found that it is great for every day use. It is not meant for large amounts but it is perfect for single, smaller brewing situations. The grind selection worked well and I "dialed" the proper ground size for my single sized pour over coffee maker.
