My 5 star rating takes the great price into account. For around £30, what more would you expect? The screen material is thin, and when not in use, you can see through it slightly. However, once you project an image on the screen, you don't see through it at all. My projector was only £80, so I'm not looking for high end results - though the images are surprisingly good. The screen is light and easy to assemble and move - despite being big! If you're looking for a budget projector set up , you'll be more than pleased with the result
