4K HD Foldable Projector Screen & Stand

I use this for events that require a screen and projector. Problem with this screen are numerous.1. The corner connectors don't truly connect to the top rail. They can slide in and out too easily, adding to setup time.2. The screen itself becomes too wrinkly after a few uses and will not stay solid resulting in a worse picture.3. The screen does not stretch across the rail very well. This is very disappointing and adds to my frustration.4. The O Rings on the top of the screen tens to break away after a few uses.Apparently, I missed my return window, otherwise I would return it.
