This is slightly longer than the original that came with my Vizio E500d-A0. The keyboard is on the back and is a big improvement over the Vizio's onscreen keyboard with the original controller. The only thing I didn't expect was that one of the preset buttons (top right) is different than the newer controllers. This controller has its own voodoo. Newer controllers will come with the new M-GO (although I'm not sure if it currently works). The battery compartment is on the bottom front instead of the bottom back on the original, and it takes a little more thumb pressure to open. .Everything else works as expected. If you use the on-screen keyboard function frequently, this controller will save you time.
