Query: it is a two persons' job to pack

The screen was built with fair workmanship. There are some sharp edges on the tripot legs which is easy to fix with a small file. When I opened the box there was a strong petroleum smell which I had to air out in the garrage. I also removed a few black stains using a dampened paper towel. Setting up is getting easier after a few practices. But when it is time to pack up it is better to do with two people. The spring is designed to stop at intervals so when it stops the screen could be damaged by accidently creased. So if you have an assistant to help you hold the bottom frame while you hold the top bar and gently lowering it in continuous motion it would be more of a success.
