We have a small puppy and have been looking for a nice gate.  Well, some of them range up to the $300 range.  Checked out Wayfair and found this one with a door!  Love love love this gate.  Everyone that comes over has positive comments about it and I can easily do from room to room without having to climb over the gate and we did not have to attach it to the wall.  Love this gate. 

Pros: attractive appearance, door opens either way, the gate is very flexible.
