Recently purchased 16 panel-pet fence. My intention was to put a lg outdoor extension for my bunnies to enjoy the fresh air/grass go in at night. (I also separately purchased toppers to keep predators out!)my husband put the first 8 panel section (let me add I did purchase from tractor supply heavy duty cattle stakes to be put behind each pin)absolutely wonderful no problem easy assembly we used a lot of plastic ties to secure pins to stakes it’s very secure)!!!
Next day started on the next section of panels
(We purchased 2 /8 panels)first thing we noticed 2 pins missing hinge on door doesn’t work properly.
The pins we could work around 
because we do use cattle stakes to ensure there would be no wind damage; the door is another issue: we’re using a bungee cord wrapped around post to keep in place 
Bec of the missing pin/door issues I only gave it a 4 stars. But trust me, I would have given 5 stars if the hinge on door worked properly.
