I am using it for TV model VF552XVT after the old model (VUR10) lost connection to the TV. I opened the box, put in (2) AAA batteries and it worked (I think you have to press the power button first). No setup required. The remote also works with the newer Vizio M-series Smart TVs. A full-featured QWERTY keyboard on the back is a huge plus if you spend a lot of time surfing the web, watching videos, or searching for content. I haven't seen this keyboard from other manufacturers, at least for a good price. It's great to have this feature. With built-in apps and a full-featured keyboard, you can spend a lot of time away from your phone for once. One feature that I found very handy, but that the old model didn't have, was the closed captions button. On older models, CC took 7-10 keystrokes to activate. This model also has a much better form factor, making it easier to grab. The button operation does not require too much pressure and is comfortable to use. It remains to be desired: the buttons are still not backlit, so the complaints remain.
