Exactly what I was looking for. I needed the extra extensions for the wide opening to my kitchen. Set up was simple for me even without instructions.  I like not having to take a gate up and down every day - once up stays up.  Opening is not as wide as I would like but that is minor.  I have small toy poodle (5 lbs) and even though bars are a little farther apart she can't get her head through. If you have a smaller teacup type bread this may not work for you (widest 2 1/2 in opening) so keep that in mind.
