We own one but haven't used it successfully. It does create the screen as advertise but our problem is we get a lot of pin wholing, etc. Our screens also broke down fast but could be due to the fact we were doing shirts in a garage (no air) and this material used for making screen is heat sensitive.
We've never actually found success with it but again it does create the screens well you just need to make sure there is NOT dusk, particles etc. that can cause pin wholing.
I have recently found an alterative idea thou that i've tried and got no pin wholing. I saw it on you tube a few months ago. It allows you to use a traditional screen and some vinyl.
