The stock response system in my DM II fell off so I replaced it with YoyoJam silicone pads, which should be the same as stock ones, right? Once I applied them (they fit in nicely), DM II turned from dead smooth unresponsive yoyo to really snaggy one. It doesn’t come back just by tugging it, but during some tricks (for example finger grind and popping out from green triangle) it winds up and smashes my hand. Binds also aren’t nearly as smooth as before.
