Iam using MI 55inch 4k led smart tv for the past 9 months , I have purchased from MI store at pattom trivandrum , one of the best product that I experienced it’s just unbelievable, the picture quality that has been used and the audio quality is also nice I have connected to a 5.1 home theater system that increase the ambiance , I have no doubt those who buy the product will not regret anymore
