Hey just looking for some suggestions for a new mouse.

[Napo5000]

Right now I use kensington pro fit full size and it works fine however. I do a lot of 3d modeling in Blender which uses the middle mouse button for the main form of movement and it only takes a few hours until my pointer finger starts hurting making work very frustrating. I was wondering if anyone knew some good options for me.
Comfort is the highest priority and I have medium/smallish sized hands if that is at all relevant.

Thank you in advance!

This is technically a workaround, but most gaming mice would work really well for this, since most come with software to be able to remap their buttons to something else. I'm a G502 user (a mouse I highly recommend to people who don't need the lightest thing ever and want a very comfortable mouse, but while people with small hands can use it pretty comfortably, it does favor people with medium to large hands), and it for example has 3 thumb buttons. What you could do is remap one of the three thumb buttons to act like it's the middle mouse button, that way you can use your strongest digit to press the button, along with those buttons requiring less force overall to use.

 

There are other mice that you can do this with as well if you don't want the gamer aesthetic found on most gaming mice, the Logitech Mx Master series I know has these features, and I'm sure there are others as well (I may or may not be a bit of a Logitech fanboy, so take my recommendations accordingly)

I would highly recommend the MX Master Series Logitech has. They have a built in thumb button (used by pressing your thumb down rather than pushing an actual button.) It can be remapped to whatever you would like it to be. The ergonomics are fantastic as well. I can use it for hours with little fatigue

logitech for sure.

nothing can keep up. 

go with a g203 if you are on budget or with a g502.
