Pro version Unresponsive Full metal Ball bearing Very long spin This is for pro, unresponsive. Need to Bind to bring the yo-yo up. Good for 1A pro tricks Aten (also Aton, Egyptian jtn) is the disk of the sun in ancient Egyptian mythology. The O2-Aten design, you may find the whole yoyo design come with broken lines~ t looks more than a strong man with strong body just like O2-Aten throw in hand. Much bigger catch zone to make your power blasting all in one throw. All solid type with dual polishing ring come in the 1st run release. European players favourite throw, you'll get a unique feeling in Aten which wouldn't loose your expectation' as local players said in the review.
