My only issue with Samsung is the cost of repairs. After 6 years, my 50 inch curved screen - remember them - started juddering. So I went to the local Samsung repair centre, showed them the pics and video I took and they said a new screen was needed, fine said I, how much? 20k said they. I said you are having a giraffe and went and bought a new one instead.
Prices are much cheaper than even a few years ago, that they are now, effectivelly, throw away items. I got a 65" Samsung for 13k. But I am fortunate in that I bought from power mall, and in addition to the special offer it was already selling for, my other half got a further 15% discount as she works for The Mall Group, then she cashed in various points from various cards, so much so, I can't even tell you what the original price was. But it was the model I wanted - with a flat screen.
