Razer's Naga Trinity gaming mouse reviewed
 

Way back in 2009—nearly 10 years ago—Razer released the original Naga MMO mouse for the button-crazy. By that time, I had already been thinking that mice didn't have enough buttons. We had all these keys under our left hand, but had to make do with just five mouse buttons under our right-hand fingers? The Naga and its 12 side buttons seemed like an answer to my prayers, so I snapped one up as soon as I found it at retail and rushed home with it gleefully. I had some frustrations with the mouse, but I used it for a good while.
