What is the frame made of?
210D oxford cloth, a tough woven fabric commonly used for outdoor gear. XHYCPY says it is durable and does not fade, and the white projection surface is a separate panel that comes off for cleaning.
How powerful is the included blower?
XHYCPY rates it at 180 watts on 110 volts and says it inflates the screen in about 2 minutes, where weaker built-in blowers can struggle to hold the frame up. It needs to stay running for the whole film to keep the screen inflated.
Does it come with stakes or an anchoring kit for windy conditions?
Yes. XHYCPY includes tethers and a stake along with the screen, frame, blower and carry bag. Tie it down every time you set up outdoors; in more than a light breeze, extra weights or stakes of your own add a margin of safety.
Is the blower loud during use?
It varies. XHYCPY says it is hardly noticeable once the movie starts, and it can be quiet, but it is more noticeable to some ears. Since it runs for the whole film, set realistic expectations rather than assuming silent operation.
Can it be used for rear projection, or only front?
Both. XHYCPY builds it for front and rear projection, with a 160 degree viewing angle and a 16:9 screen ratio, and the picture is good either way. That gives you flexibility depending on where you want to place your projector relative to your audience.
How stable is it if there's any wind?
Stability is a mixed point. It comes with tethers and a stake, and tied down it can stay put in a light wind, but more wind means more movement, so add your own weights or stakes in breezier settings.
