- *****- Feedback left by buyer.More than a year agoVerified purchaseThe materials and quality of this 120” screen are outstanding. The packaging is first rate. The assembly instructions sheet is not user friendly. Fortunately, there are 2 or 3 good YouTube videos available on how to assemble and mount the screen. Seller was terrific, contacted me to confirm what I had ordered on line was what I wanted. It wasn’t. They had what I needed and refunded my first order within the week and filled my new order with the correct product.Reply from: gmaxsigns- Feedback replied by seller gmaxsigns.- Feedback replied by seller gmaxsigns.Thanks for your feedback.
