How to Build a Home Theater with Vividstorm Screen and Laser UST Projector?

Hi, there!

I am going to build a home Theater.
I am looking at VAVA laser UST projector and Vividstorm screen recently.
I saw a lot of review video about Vividstorm screen on Youtube.
The introduction is quite good, the picture is clear and Vivid.
I saw there are sell on Amazon and Alibaba and some other shop.
Is there anybody who buy it from China directly?
Do you have experience to share?

Thank you!
