I have never used, nor even seen, a vinyl background such as this one...

I don't like muslin because of the wrinkles and canvas is heavy an unwieldy to transport.
Digital backgrounds are cheapest but can be a PITA to use.
Has anyone used a vinyl background. How does it look? Are there fold marks? Reflections?
The price is inexpensive but, IMO, you usually get what you pay for.
If I ordered one and didn't like it - it would be expensive
