From functionality point of view this wind sim is very good. It works perfectly with SimHub and provides very strong wind depending on the speed of the car. Big thumbs up in that regard. I also like the black look combined with the colored duct ends, looks very slick.
My main criticism is more or less related to the mounting: Some of the 3D-printed parts are very delicate, especially the hinge of the fans. I didn't apply any excessive force when adjusting the fans angle but on one side the hinge broke off from the mounting base, so I had a loose hanging fan as a result. I could fix this with super glue and now it's fine again, but I wanted to point this out as a build quality issue.
Some minor critique: The holes for mounting the fans to the rig are bigger than the washers that were provided - I had my own washers lying around that I could use, but I just want to point that out. And also the fans get fairly loud on stronger settings, it's pretty much like a vacuum cleaner, just keep that in mind, if you have other persons in your household or even sensitive neighbors, if you want to run the wind sim on stronger settings.
All in all, I really like this wind sim kit, it provides additional immersion to the driving experience in the sim in a ready-to-go package, in that regard I would give 5 stars, but due to some build quality issues mentioned above, I have to deduct one star, so 4/5.
