The grinder works but there are a few things do not work for my expectation.  The glass container is not static free.  Grinds are flying everywhere when I slowly pull out the glass container.  The on/off timer can only work 20s at a time. I should be able to bypass this for longer time.  If I adjust the grind setting to French Press, the vibration caused the conical to move to the unlock position.  This can potentially cause the plastic conical to fall out of position and spill the beans or turn off the machine at the least.  Also, the glass container is very thin made, which it would break easily.  Not sure if I can buy a replacement for that.

Pros: compact, easy to use, color choices
Cons: flimsy made, short timer
