I don't sell any of these nor do I receive any remuneration if you buy them, and I have not personally reviewed all of them, they are listed here to give you perspective
Introduction
uncommon in Australia
two poles which cross over each other twice creating an X at each end
doors are sloping in towards the ceiling which can be an issue if you need rain protection but want to have visibility or ventilation (you may need to add a tarp or place under a gazebo)
supposedly strong in winds and for snow conditions (if they have a narrow ceiling and are otherwise built strong enough for wind and snow)
