It was a Vizio 55" E-Series. There was no Ultraflix on the box. I bought a Roku 4 also(I had to download the Ultraflix app on that) I'm not real tech savy, but when I have more time I'll check to see if Ultraflix was pre-loaded on the Vizio. I bought the TV at Best buy for a little over 400 dollars. The salesgirl knew nothing of Ultraflix. I told her about it and that they had the largest 4K library available. I spoke to another salesman who said he heard of Ultraflix. I think if theses sales people were educated somehow about Ultraflix and the deals going on our revenues would grow much faster.
