I had previously order this same product from the world's largest on line retailer. It took 5 weeks to ship and when it came only one of the three expected boxes arrived (the screen) and it looked like it had been shipped around the world.
It took two additional weeks to ascertain that the rest of it was "lost" and to get my refund. I found the same product at Projectorscreen.com for $1300 less, it shipped and arrived in less than two weeks and they kept me updated along the way.
When it did arrive it came in two boxes, both in great shape and with the manufacturers logo on the box. Everything was fine.
Take your time putting the screen together and it helps if you have a large clear area to work.
The instructions had a couple of small mistakes (drill bit size too large and reversing the horizontal and vertical fiberglass rods) but a little common sense goes a long way.
The picture is clear and bright. I can't comment on the audio since I am not using the built in speakers/subwoofer.
