The delivery of this item came from Penn. and traveled thru at least 6 states before getting to CA. The box was pretty beat up and retaped several times, but the greenhouse parts were in good condition. The assembly instructions are almost nonexistent, no written instructions. Halfway through the assembly we had to take it apart and start again because we misinterpreted the way the main posts were supposed to be facing in order to complete the top. (Take a good look before starting). The finished product is very sturdy, plenty of boards for the plants and the cover is made of a thicker material than I expected. Overall, we are very satisfied with this greenhouse.
