I've used this now several days for my morning cup of joe. I freeze my beans and drop them into the grinder frozen to make my grind. There is a button to press while keeping the chamber closed which is nicer than models which start when you close the chamber. It lets you press the button 3 times while letting the big beans settle back to the bottom to be cutup. I normally grind, stop, shake, grind, stop, shake, grind, stop empty. Cleanup is really easy to remove residual powder in the grinder with a paper towell. Cord storage is also very easy because you can wrap the extra cord in the base of the grinder. It arrives with the ENTIRE cord stored in the base of the grinder (about 2.5 feet). For safety I always clean any grinders with the cord unplugged.
As for the motor, it is smooth running, the blades are well balanced, and I expect a long life. I had to buy a new grinder because my older brand name unit broke the top when dropped. I did not like the top cap being used as a switch on that older brand name unit because it would let grounds escape when I use my 3 step grind to get all the big pieces down to the blades.
The grind size is proportional to how long you hold the button down - about 3 one second bursts are sufficient to make beans into grinds for a drip maker. A little more might make cappucino (sic?) grinds, but I'm not that exotic. It's a great price and a bargain compared to what I paid for a worse design years ago!
