Greetings.Quick question, do all razer deathadder v2 pros have the rattle sound when shaking it ? Mine has this issue too I found out that its the dpi buttons that make the noise, whenever I press them in and start shaking it I would not hear the sound.I saw in a youtube video from Rocket Jump Ninja (with a v2 not pro version) that not only mine has this issue, I don't know how it affects the mouse integrity or quality...thanks in advance for the response.
