A very novel gift idea. Enjoyed the ritual (and aroma) of hand grinding beans. Grinding mechanism poorly made (flimsy shaft and plastic grinder). Broke only after @ 10 uses.
Takes a lot longer than an electric grinder but a great backup ; plus it looks very unique.
I was looking for a simple coffee grinder that was adaptable to a ball jar. I had my eye on those steampunk contraptions but this one looked simpler and was less expensive to boot. When it arrived my husband had to take it apart as soon as it arrived to get it to work. It still sticks, is hard to adjust and grind, and the threads on the lid don't even match the ball jar--you have to mess with it for a good twenty seconds to put the lid on the jar. It seems like one of those gifts people give someone because it seems like a great or fun idea but the gift itself is just cheap and hard to use. I want a refund.
A good universal grinder that I know I'll get a lot of use from. My electric coffee grinder upsets my dog, and disturbs the whole house. With this I can quietly grind a fresh basket of coffee in the wee hours and let everyone sleep.
