The screen has no tubes on the sides, which causes the sides to sag a bit. This means you don't have a nicely taut screen on the sides. If I were to buy something like this again, I would buy a screen with tubes on the sides as well. But it is a cheap and large screen for this size. If you turn off all the light and watch the movie, you won't be bothered much by this.
The screen also arrives folded, so you need to iron it out a bit before use.
