The box was damaged in shipping, and the grinding parts were shoved together so tightly that I had to take the entire thing apart and put it all back together to get it to move at all. It took a few tries to get the grind size adjusted to what I am happy with, and it works fine. It fits well on the jars I have already, but it will be the backup for the other hand crank grinder I already have, which was much more expensive and built better.
I would prefer if the wooden handle was screwed on the crank instead of riveted, it does wobble more than I am comfortable with.
There is a silicone feeling cover that comes with it, and we keep that cover on it while grinding to prevent the beans from escaping. I even went as far as banging the side of the hopper on my counter to see if it was sturdy and it was great. It didn't lose any shape at all.
We make one cup of coffee at a time in a pour-over cone, and it holds enough beans for that, but I don't believe it would hold enough for a full pot.
For the price, it is good. There is better out there, but better will cost more.
