It was easy to set up and install.  It works well and seems pretty sturdy.  I don't love the locking mechanism.  If you want to keep it firmly locked, you need to use two hands in order to open it (one to pull the red locking piece over, and the other to pull the white handle up).  I don't keep it firmly locked since it is just to keep my dog in place, but a toddler may be able to figure it out.
