num pad locked on the side of the mouse, you can change it to be the top number bar or the num pad, the software does not have a config option like the N52 does, hopefully they will release something to that effect later.

Seeing i already used the num pads for macro commands switching to the naga was insanely easy for me.

The naga is slightly smaller than the G5, however there isa finger rest on the right side of it which helps, i would have loved for another button to be placed on the right side, but no luck.

There are 2 bonus buttons that are near the left button on your pointer finger, everything is responsive and easy to use. Getting used to the keypad is the biggest change and requires some thumb flexibility

I would have liked the naga to be slightly larger, the key pad forward about half an inch and a button on the right side. One thing i do miss is the speed control on the G5, which was awesome for switching scroll speed on the fly when in photoshop and FPS shooters (headshots baby)

This thing works great with the N52, i everything i need is now on the mouse or the n52.
The razer addon sucks ass, its a cheap ripoff of dominoes
