I tried the G600 under the idea that I may not use all the buttons, but it would be nice to have some extra buttons when needed. I returned it a week later.
Some people actually like it, but here are the problems I ran into:
- if you need to pick up the mouse and move it to continue spinning one direction, I often hit other keys I did not intend to. It is very difficult to lift without pushing a side G key.
- There are so many buttons, it is hard to train yourself to instantly push the right one when it is needed.
- I could not program the G keys to shift/alt/ctrl, as the ring finger button is designed to apply a shift state, which means that it is only available on the ring finger, which allows for all other G keys to act as a shift+ or ctrl+ key when it is down.
- Even the ring finger button made things a little more difficult, as you now have to lift the mouse with only your pinky, which made it difficult to keep the mouse level as I picked it up. This is partly why I'd push side buttons on accident.
I replaced the G600 purchase with the G700. 4 thumb buttons is enough. It even has a few extra index finger buttonss that are easy to reach but not get in the way.
