Hi, I just bought a new Sundia Icy Triple Bearing Diabolo, and when I speed it up real fast, it vibrates a lot. The cups are stable, the diabolo doesn't tilt/turn, but I can feel a vibration through the sticks. I have other bearings, single and triple, and they all have some degree of vibration but not nearly as much as what I'm experiencing with the Icy. Wondering if anyone else has had similar experiences, and if this is a problem or just normal for the Icy?
I've tried tightening the screws, that didn't seem to have any effect.
Thanks
