The spinner is nice and light. However, the cut-away area for the blade holders was inaccurate and carelessly done. The edges were ragged and the prop holder screws did not align with their holes in the spinner. I had to do a lot of cutting and modifying to get the spinner mounted. The result was unsatisfactory because the openings for the blade holders were much larger than they needed to be, which increases drag. In summary, I was surprised at the poor detail work on this spinner.
