It's a good size and easy to build up once you stare at it for a while and wish that it came with instructions and it does the job but even in the picture of it on this page, look at the draped curtain in the middle and see those creases? You'll also have them. I can't take flawless background pictures because the material is really thin and the creases show up on each shot. What I have done is purchased thick plain white wall paper and draped a sheet of it down the middle to achieve the seamless background. This works but that means this is not a one stop product.
If you are prepared to source a new sheet for the inner drape, then this product is good but like all cheap photography products, the creases from folding all the sheets are a nightmare to get rid of.
