The Predator smart disk was a very popular item, and I did take in all your feedback and designed another one. This is not an update, it's a different version. The first one was more for a heavy hunter but this one is much thinner/slimmer, has longer blades, and i added an extra little design touch to it, the hollow middle, so it look even more "alien" I'm doing a little comparison video on them as well, so will post that one soon. The new design also allows us to hold the disk in a different way, but you can see that in the video here :)
