the roccat pyra wireless sucks
its rechargeable battery cant even last for few hours, web browsing only
when the battery is low, the mouse pointer start to teleport randomly, its very annoying
the provided cable charging rate is slow too
the scroll button is so hard to press (i use it to open new tabs)
the built quality was just soso
hand grip and dpi was OK, but the battery and middle scroll button problem make it a bad mouse
