I had to purchase a projection screen for my office and decided to go with . JD in customer service was great. If he did not know an answer to something he would take the extra time to find an answer for me. He also went through the different variables of the room the projection screen would be used in and what type of projector I would be using on it. Lighting control, seating positions, angles, and screen contrasts were all discussed. It was a good shopping experience and they gave me free shipping! I love free stuff! Talk to JD if you call in. :)
