**I purposefully waited a couple of months before writing this review so I could share my results over a long period**

I bought this mouse as I use audio editing software every day for work (at least 8 hours).

-Comfort

Firstly I wanted a mouse that would be comfortable to use over long periods. What I have found so far is it is a huge improvement over the apple mighty mouse I was using for years previously. My hand sits nicely on the top of the mouse and I don't find myself stretching much at all. I like how you can finely tweak the DPI (sensitivity) of the mouse to ensure minimal hand movement. There is a nice weight to the mouse which also seems to help give smooth tracking. It doesn't seem as heavy as the Razer Naga with 12 buttons which I tried also.

-Functionality

I bought a mouse with extra buttons as I wanted to be able to program useful shortcuts and macros that I use all the time in order to speed up my workflow. I chose this mouse because I think that 7 buttons is about the limit for me to be able to use quickly and still be able to remember what is assigned where. The 12 button mouse seemed far too squared together and I would often hit the wrong button. The 7 side buttons are nicely spaced and the circular pattern makes it easy to recall the macro you want without looking at the mouse.

I find the Razer Synapse software very easy to use and it's super quick to record new macros. I have a couple of profiles at the moment, one dedicated to my pro tools software and a general one for browsing the internet etc. The software automatically switches profile when I go from pro tools to safari for example.
