update: after only 7 months, the screen becomes wavy and wrinkles appear in the corners. You can see this beginning in every photo I take. The screen was originally flat and solid after assembly, but that's no longer the case. Big disappointment as it doesn't look good. Customer service was very responsive. They send me replacement parts that will hopefully fix the problem. This screen is expensive. However, you get what you pay for. I have paired a CLR 4 with a VAVA ultra short projector. It easily rivals my recently purchased 85 inch Sony TV for clarity and colour. The screen looks like a giant flat panel mounted on the wall. Even when the projector isn't on, it looks good. The screen makes a big difference, especially in terms of lighting and viewing angles. In general, the assembly is quite simple. They have a YouTube video that is pretty easy to follow. You need 2 people to set it up.
