the only issue we have is that the remote does not have an 'exit' button and 'back' can't get 'cha out of it. Using a remote from the other two Vizios in my opinion is no no.
I am so in love with the Smartcast feature!!! I have owned several Vizio tvs over the last decade. Always passing the previous model on and upgrading. I'm so glad that I found this model and it sits beautifully in my living room.
