I own the DM2 and I feel that it is not living up to its potential. I am unable to perform string tricks in one combo without the yoyo dying out on me. It is very annoying. Other, less popular yoyos I own, are doing more than my DM2!
If anyone one has any advice or tips for me, to either add something to my bearing, so I can complete longer tricks like Black Hops and Cold Fusion, please, comment.
