Query: Optics is ok but low quality control in production

Right out of the box, It seem to be good quality for the price. But When I try to view through it. It is bright and sharp enough but I can see a few specs of dust. Upon close inspection, I saw a few dust under the big lens and also one big dust under the eye piece. It has such a poor quality control on this binoculars. I don't know it is only the one that I have or not but I do not want to get any of these anymore.
