I got a benq w1070 a while ago, projecting it on a plain white wall, but I have been wanting to purchase a projector screen for it, but the prices here in dubai are outrageous due to shipping from the US (there also seems to be no local shops that have good screens like EliteScreens, Daper, etc) but only the cheap knockoff chinese screens.
Anyway I came across this new projector screen paint from the UK, it has very few reviews, is pretty recent, so im a bit sceptical, although my choices are limited. The only affordable paint here with the shipping cost ($22) appears to be this one. Anyway, ill link the ebay page, the website, and the youtube page showcasing the product.
Obviously, I would appreciate your expert opinion, wether or not it is worth buying the product.
Also, I need to specify that my room is light controlled with blackout curtains, however, the top/side walls have not been painted black, they are white, and in the video showcase they obviously have black walls to control the light, and it prevent washing out the picture , so their results must be better. I cannot paint my walls in black as I live in a flat, will I still get decent results with this paint?
