Interesting find - that certainly
is novel! Feels a bit like 'innovation' for its own sake, though, at least to me. More of a gimmick than a real advancement in design.
Don't see any benefit to the design, as just about any airbrush compressor on the market already includes a handle. Also, it doesn't appear to take up any less space than a traditionally tanked model, thanks to the angle of the tank-handle's upper extension. If anything, it's a lower capacity tank in the same amount of space.
Seems somewhat awkward to use, too, since the airbrush holder is on the opposite side (and facing) as the regulator and outlet, with a tall, chunky bit of pipe between them.
Still, it's something I hadn't seen before.
