We use this for our dogs and have this blocking our kitchen off and use it daily.  It is easy to install and operate.  I have a 6&7 year old and they operate it with ease as well.  Only negative is the small pin for the little door fell out and got lost.  Since we don't really need the little door, I zip tied it and it's fine.  If you plan on using the little door a lot, you may want to be careful.  Overall, a great gate, much easier to use than the plastic or wooden ones you have to fasten into doorway each time-my dogs always knocked them over not matter how tight we got them.
