ROCCAT Leadr Wireless Multi-Button RGB Gaming Mouse Review
 

While the multitude of button placement may discourage some mainstream users but also entry-level gamers and would state they will never use these or are somewhat hard accessible, this is not the case! ROCCAT made sure that the button placement is optimal and we have had absolutely no problems accessing the ones placed on the left panel with games such as Kritika Online or Black Deset Online. The sets of buttons on the left and right side of the usual left/right click buttons need some time to get used to, while the Easy-Shift[+] function button can be accessed very conveniently.
