Deathadder Elite - problem or no?

Hello my question concerns the Razer Deathadder elite which I have the pleasure of using today, the mouse itself is wonderful but I am worried about 2 things and whether it is a product feature or my product is defective, my first concern is that when clicking the right button is softer and quieter than the right one and my second fear is that when I tap the right button very gently, a knocking sound is heard (it is not loud) maybe someone has had this mouse and knows if it is normal because I panic a lot. Maybe someone has Deathadder Elite and would share their impressions.
