Naga X clicks and mouse wheel sound issue?

Hey people! just got my new Naga X yesterday and when i started using it i wondered if that's how it supposed to sound like or there's an issue with mine. might have to up the volume in the vid as it wasn't as auditable in low volume in the vid as it is in real use. with M1 and M2 there's some additional noise on top of just the click sound. like something disturbs the plastic and it hits something. and there's some grindy sound to the mouse wheel when moving it forward. is this what this model supposed to sound like? Thanks in advance for answers and advice!
