what's wrong with Chinese brand tablet?

Chinese tablet is cheaper. What is the major difference between Chinese tablet and Korean tablet? thx

For korean tablets ,if you mean lg and samsung, there is almost no difference in almost all factors compared to very good brands in China, although i dont know any good make ,even though they may have been made in different countries , but the korean brands are usually very well recognized globally ,these multinational has already built up a good reputation for their products, but the chinese firm products are usually not sold in the international channels , it is an emerging market that has just started expanding , but the chinese firms are known to sell products at a very cheap price , this makes people speculate the quality as they are not used to these prices , the after service is doubtful as well due to the idea that they are not multinational firms , they do not have the duty to give great service as they are not as well reputated
