There are much better and more comfortable mice now. Logitech's MX line of wireless mice are more comfortable and precise. Their gaming mice are also better if you prefer wired.
The toggle-able free-spinning scroll wheel on the M705 was a game-changer for me. When I got the mouse, I was working for a place that had a lot of buggy spaghetti-code programs that interfaced with a massive database, and I often ended up manually scrolling through million-row tables in Toad correcting broken or missing data. It made my life sooo much easier.
I later upgraded to a MX Master ($100) which automatically enables free-spinning mode when you scroll quickly. It's fully adjustable, and it works super well.
I use this one as well. I think it's my long term choice. I got one for work and home. Battery lasts ages, wireless is pretty good. I do notice that a big ol' wifi router next to it will interfere...
