Hello everybody! This might be a wierd question but ill ask anyways! So like i have a northstar yo-yo and like i just wanted to know when to replace the response system which i think are slim pads? If someone knows what it is please tell me what it is. I know when friction stickers are in need of a replacing but since this is a new response system that i am using i dont know when to replace it. Thanks for your answer!
It is yoyofactory pads bought here: YoYoFactory Response Pads – YoYoExpert
And when you look at them and there is a deep groove going down or you bind and the bind slips and is very hard to bind then they are ready to be changed.
yep what dingo said, if your binds are slippy, or if they fall out, it’s time to change em
Don’t overuse like 
CBC Slim Pad Size 19mm
Or flowable silicone 
i only used like 2 times 
Haha I know
