I recently bought this screen in the 150 inch version. It has a reflectivity of 1.1 and is perfect for our room. At nearly 11 feet in diameter, it fills an entire wall for a reasonable price. I don't know where you can find a better price for this size and quality. One downside is that it doesn't retract properly due to its size. I bought two. The first one may have been opened earlier because there were some abrasions on the end caps from grinding. I was a little upset and then realized the screen wasn't removed due to cosmetic damage. Even taken from the ceiling and held upside down so that the screen was over the coil, pulling the screen back to account for gravity wasn't enough. I returned the screen (thanks Revain) and bought a replacement. There were no scratches and it was removed. The spring force isn't enough and you really have to push (push) the screen up. I take it as is but I would prefer a little more retraction knowing its durability will diminish over time. Also, both units had minor shipping dents and I assume this will be very common as the package is 11ft long
