Input:
After reading the reviews on this pepper mill, I ordered one. The first time I took the top off to add pepper, the entire top fell apart in my hands and a small square nut plopped onto the floor. I tried several times to put the thing back together but to no avail; it just would not work! Disgusted and disappointed, I contacted Amazon and sent the mill back.
