Vizio gets to the low price by not worrying about spares and repairs. That's a big savings to them and lower prices.
Not much to add here except the price would be cheaper than other brands so you are basically renting the TV.
I have had my vizio for 2 years and suddenly the picture is black on the left hand side. I called vizio and I was told to buy a new tv. It wasn't cost effective to fix it. I just spent hundreds of dollars on this tv! I have never purchased a tv that lasted less than 10 years. Vizio products are terrible and service is non existent. Tell your friends to SKIP this product and go for something better made with a good company to back it. Looks like my christmas money will go to purchasing a new tv instead of gifts.
