i have not even had my g5 for a day and it is responding, what do i do
Give the bearing a little drop of oil and break things in.
it wasnt responding when i got it though
It’s called break in.
Clean the bearing if you’re impatient.
First off calm… Ok I have a G5 and at first they are a responsive. Why? You ask,I anwser… The response system is brand new you need to break it in. try binding of a trapeze this will wear the response. Second make sure you are using a clean string, also keep yoyo properly lubed for a while. I all this doesn’t work just reply and I will help you more! 
thanks
No problem!
