Zipper tabs broke on the first closure, but a paper clip can fix that issue. Instructions are very small and not very clear. Not so easy for one person to assemble it. You will also need a step ladder if you are under 5' 10" tall.Make sure it is locked don't since the wind flipped mine upside down during a storm, so now I used wood spikes about 4 inches into the ground and tied them to each vertical frame to keep the greenhouse down and secure. Otherwise, the plastic material is not bad, and it keeps the temperature inside about 20 degrees warmer than outside.
