Kaiboer - unbelievably this brand plays ALL files, even those that Chill, Med8 and Cinema Tube can't play. If you have MKV files that your current player cannot read, you should try Kaiboer because it reads every type of file I have tried it with. Am not sure though how durable the product is. But at 3,500 I think it's worth the gamble. My 2 cents.
