The portable carport was easy to install, directions were well written.  Once installing the cover there were a couple of spots on the roof that were stretched out with the possibility of leaking, I covered the areas with another material to prevent leaks.  The sides all the way around are open to the ground, so weather can enter the portable carport.  I installed 1"X4" boards all around the carport and attached them to the cover to prevent this problem.  Would not purchase this product agan due to these issues.
