I got this for a new TV my Dad got, the TV is a Vizio 32 inch LED set. While putting it together was generally pain free, it wasn't frustration free, as I was the only one available to put it together and some parts of putting this together definitely needs 2 people. Still, it took a day longer to put on the finishing touches as the "universal" hardware that was included didn't come near to the size screws I needed for the back of the tv. I don't know about other Vizio sizes but mine needed the M4 screws that I ended up getting the next day.
Over all it wasn't horrible to put together, just a bit taxing on the nerves. :). But the base itself is very steady which was the goal for my Dad's and the TV's sake.
It still would have been nice to have had a selection of some smaller screws to test for the fit with the TV
