I've recently bought the new Microsoft Intellimouse pro and Its quite to my liking.
Have used a 3.0 in the past and always loved it.
My previous mouses were:
- Razer deathadder 2013
- Razer Deathadder Elite
- Zowie Ec1-a
- Intellimouse 3.0
I still like the ec1-a the most, but it has major coating issues.
The intellimouse pro is light, cheap and has a good sensor. I don't know what a dedicated snipe button is, though.
