Windsible wind tunnel, anyone use it?

At this scale aerodynamics doesn't  make a difference. It would still be fun to play with a wind tunnel but using one for gaining any perceived competitive edge is a mute point.

Yes, I bought one in January. So far, it functions exactly as advertised. Since I find fluid dynamics to be intriguing, it's easy for me to spend an hour examining different vehicles in the chamber. Cars with adjustable spoilers/wings are interesting too see @ various angles. I can also compare the size of the lateral wake with different front ends. But what the device does do is either comfirms or debunks(at least to some degree) what was previously just speculation.
