My wife installed this in her 2011 Porsche Cayenne.  It went easily and she commented it was of good quality.  Installation is best with 2 people as it's otherwise awkward in adjusting the height.  I have 2 Samoyeds and one of them is a chewer:(.  So... the knobs were chewed on the first day but they've survived and fortunately my dog seems to have stopped chewing on them.  The barrier works perfectly in keeping the dogs in the trunk area of the SUV.  I also liked that it's not attached to the seats which allow you to occasionally lower the seats to carry skis and/or other big stuff.  5 stars.
