I really like Gunze products in general, when I saw this product that they say is made specifically for in house aibrushing I wanted to know if anyone had used it or at least know someone who does.
I have a homemade booth but the noise and cumbersome handling whenever I have to move it makes it seem well worth the $225 investment.
If you do a search under Gunze Booth or Mr Super Booth you'll find it. It's an open air design with some covering along the sides to protect from overspray I guess the idea is to spray the model directly in front of the filter. I also like this because I can then design a booth cover for it.
