Ministreak question!

Hi guys!

I’ve a FNC ministreak and i always love the poor sound and the good feeling with the button, it think it’s almost 3y maybe 2.6

Lately some button are giving me trouble and I was minding if someone can give me advice on how to try and fix it before getting a new one.

The problem is that some time they miss the input, I know it can be many factor but maybe someone can help!

Ty very much and always fnatic
