After extending for the first time, there was a weird chemical smell

so unfortunate.- Has a very strong chemical smell that filled my living room as soon as I opened the box- Retracts very very slowly and doesn't catch well

A second point is that the screen material has a strong chemical smell, which I hope will dissipate over time.

What I didn't want is a toxic paint chemical smell that is coming from the screen

My son has a kidney problem, I really worried the chemical smell to my family

Like all others have said there is a noticeable chemical smell when you first take it out

It did have a noticeable chemical smell for the first three days but nothing since.

It does have the very strong "chemical" smell the first few days, but it has gone away

Those couple inches extra on the model C might not seem like a lot on paper, but are visually a VERY large difference.

my only gripe is its hard to pull down to the same spot every time actually almost impossible and if you pull down just a little to far you start to hear a ripping type of sound that made me think its easy to break as I pulled very gently but overal it's good as long as you leave it down most of the time of can make your projector image move up or down slightly with ease

The picture on it looks crystal clear, in fact as good as my 1080p "55 in.

Other than being an absolute challenge to hang as it is very long and require heavy duty mounting supplies, it works awesome

Lucky for me, screen had no issues and it works as it should.

The screen does show some horizontal lines when very bright scenes are shown but that can be easily toned out if that stuff doesn't bother you, bothers me a

I have no idea how well the screen works as it was delivered damaged.

that's why we used the hanging l-brackets.
