When we go to online stores to buy something , what do see often - the reviews that are written by other people about the product then we buy the product . Even if some product is of higher quality but has no reivew written in it , we don't buy it. And if new and better product comes and we can afford it we dump the older one and choose new.

Similar happens with women while choosing men - They go for only those men who have preselction or have recommendations of other women . And if a better product ( man ) comes around women dump the previous one the choose the newer.

Men are nothing but products (literally) to women.
