Can someone tell about Hand Crank grinders. I know they are most inexpensive and easy to use grinders. Do they make good grind? Are electric grinders better than these?

Yes, they make good grind, but because they a hand grinders, they are not convenient for use, in my opinion. You have to grind beans with your own hands and you will not depend on any griner settings, but spend to much time from grinding. Well choose what is better for you, speed and convenience or something else, like the process on grinding and making your coffee fully with your own hands.

The grind depends on how you make it with a hand crank grinder

It is better to use electric grinder because you will just make necessary settings and make the proper size of grind for your espresso.

Yes, that's true....\r\n\r\n 8)
