Pros: Works well
Cons: No way to hook
We used it for the same thing as the previous poster, to go across a large entertainment area (tv, stand, dvd shelves, game systems) and keep baby away from those.
It worked well. We sort of bent two sides flush against the wall since there was no way to hook it to the wall. It never fell over on a one-year-old who used it to stand up.
A bigger kid probably wouldn't be kept out by it.
