I bought this gate before my child started walking.  I'm glad I got the extra tall because my son became a climber.  But he never escaped the living room, thanks to my awesome gate.  After I no longer needed it, I passed it on to my friend who had a little one starting to walk and he has not managed to escape it either.  Very sturdy (I did have to use the screws to mount in the doorway because I have a rowdy boy) and reliable.  Gave me peace of mind knowing I could run to the bathroom or to grab something from another room and my child was safe inside his gate.  Highly recommend!
