Except for the shipping the product is quite good. They are running on a self made turbine already now. I do not know the performance yet.
The shipping was packed a bit clumsy: the three blades were put on top of each other with some tape at both ends and had very much space to move through the box. Due to shocks there were some scratches on the surface of two of the blades which I accepted but is not good for the performance. Next time I would prefer to have shock absorbing plastic foam between the blades.
About the product itself: I think the blade foot could be made more accurately (some of the holes were a bit ovalised). The material is unknown (something like ABS) and I would like to know the strength and other specifications.
The aerodynamic profile seems a bit too sharp on the nose which is quite exceptional. I think rounding it by means of sanding would improve the performance but I didn\'t do that yet. While running the blade seems more noisy than necessary but that is not based upon measurements.
Despite these things I think the price-performance of the set is quite good.
