Always on the move for professional reasons, this small portable screen easily allows projection in a room (with table ...) from 3 to 10 people. The bag is a great asset and the quality seems correct. the canvas is slightly curved on top but everything very well. The price I think could be much lower but it is a good product that passes easily in my medium sized suitcase (or still air) For a room of more than 10 people, prefer the model Epson (Epson 65 "/ 74" / 80 "projection screen Multi-look 80-inch (203.2 cm) 4:10 p.m. / 16: 9/4: 3) Mobile also but heavier (11 kgs) A definite plus especially associated with a ultra portable video (Epson EB-1776W) and a Macbook ... I recommend!
