Quick Spin fletching anyone using them?

I was looking for some info on someone using them. Is it worth refletching my arrows or is there not much of a difference in their flight. They are advertised to tighten groups, just wondering if it is true. Any feedback would be appreciated.

My boss uses them and he claims that they work. He also claims that if it is still that you can hear them spinning? Not sure about that but he gave them the thumbs up.

They definately spin fast...I was able to slow down a video of my arrow shot and you can see how fast and tight that spin is....now as far as tighter groups....ahhh thats on the shooter....

Been using them for 2 years, they work well. I've ruined more arrows since I started using them. don't try & get a tight group, aim at differant spots. You won't ruin as many arrows.
