Seems like a great gate - well-made and durable.  The mechanism to open it will take a little getting used to for the grandparents, but they are happy that they don't have to worry about the baby and stairs.  I will say that it was a little tougher to install than the Wirecutter review implied - you definitely need longer/better screws than those provided and, while it was great to be able to install at an angle so that both sides are in a stud, getting things lined up perfectly took a bit of work.  If you have a straight across wall or doorway, it should be much simpler.
