Query: Bad Grider, never buy it!

I bough this Grinder since it claim to be sesame grinder, but after I used it I found the sesame powder from it is not acceptable for food, they are too rough, I'm not able to eating it neither my baby, and also the grider plate (2 peieces to crack sesame is platstic, the will not last long!) btw you have to buy 4 AA batter.
