I am not a techy im not into hi-fi, I just wanted a smart TV at a reasonable price. I found one at richer sounds I signed up for there free 6 year guarantee with some apprehension. Just before Christmas the TV developed a fault when i checked the TV was purchased April 2019 I contacted richer sounds and after they confirmed the fault ,they advised me there authorised repairers would be in contact. The next day the TV was picked up, the next week it was returned on the 22 Dec. in full working order, free of charge amazing. At last a company that stands by there word. I have nothing but praise for richer sounds and will not buy another TV from anywhere else.
