Although personally I think it’s a little outdated compared to other YoyoJams currently, it’s been available for at least 3 years. If you’re looking to buy it, in my opinion I would not recommend a Dark Magic over a Revolution. A Revolution is responsive out of the box, so it’s good for beginners, but the bearing can be easily changed to the other bearing in the package to be unresponsive.
I am sorry but I guess you’re wrong. If you pay attention to all the videos you’ll notice that sometimes Andre shows the “insides” of the yoyo and there is a time that you can notice that he has a konkave bearing and other time (don’t know if it’s the same) that he has his DM siliconed
