Overpriced Chinese junk.  Find a better option!
When the box arrived, I was amazed at how light it was.  For $80 I expected something substantial, but this is flimsy.  The size is good, but that’s the only positive thing I can say about it. The clunky extension design is basically a screw with a little nut inside a crudely routed groove and the whole thing sags in the middle.  Don’t believe the photos. I had to add a support (not included) to keep it from sagging.  Also one of the footings has to be glued to the gate because the thing was so loose.  Clearly, I expected more quality, but that’s a risk you take buying online.
