Packing: good, no complaints!
1st impression of the screen after unpacking: Solid rather well finished especially for this price.
Snap: Easy
first viewing: This is where it complicates it, the screen is not taut, the apparaisses waves on the image (especially on tracking shots). I left the place some day and some night screen thinking it will improve things, but nothing worked ... After a few tries I realized that by leaving the bottom of the screen bar rest on something, the waves disappeared. So problem solved!
Then the point I was making is on the coating of the fabric that tends to shine and reveals the frame of the canvas on white images. It's a little uncomfortable but not unwatchable, far from it! (I think with a more significant decline is less visible defects)
3D Printing: There nothing to say, all the little flaws mentioned above does not shock at all due to the fact of the magic of 3D!
Conclusion: For this price (the cheapest I've seen so far) quality is very decent and more than enough to start in the grandiose world of home theater. It is not a screen that I will keep for years but for now that's great!
