We purchased two gates for the two entrances of our kitchen. Now our dog is living in a gated community,   We can now enter and exit our kitchen easily and the puppy stays where we want him to be. Not difficult to install. One gate used part of the includes extension.  Looks very nice. The puppy can not climb the vertical bars. Made of metal so he can't damage it with chewing.

  

Pros: Easy to install, very sturdy, can't be climbed up because of vertical bars. Metal can't be chewed like a wood gate.
