Buy a 50 inch Smart TV HISENSE. I had problems, I demanded the guarantee and they told me that I should take it to Lomas de zamora to repair or change it. In the warranty I was told that it took 15 days for the change or repair. It was delivered on March 25. To date, 1 month, they tell me that there are no spare parts and I still do not have a TV, which I also use to work because I make graphic design. I claim almost daily and they do not give me a solution. They are a disaster
