The remote was lost for our Vizio and all our phones couldn't function as a remote with any app (no IR blasters). I've seen reviews of this product saying they just put the batteries in, point it at the TV and it worked. And it just worked like that! The remote control is identical to the one that came with our TV and our TV is definitely "old". He must be at least five years old, but I'm not entirely sure. I would buy again (if needed)!
