I am right handed. As most people do, I enable the left click with my index finger, and the right click with my ring finger. The mouse is fine except for one problem. When I left click, most of the time the mouse right member does not depress fully. I usually have to depress it multiple times to get it to work. Sometimes I have to use my middle finger to get it to depress fully.
I can't figure out why this is happening. The mouse is about the same size and shape as the ones I have been using. I have been using a mouse for a long time and have never had this problem before.
I have been using it for about 6 weeks now, thinking I would adapt to my new mouse and the problem would go away. No such luck -- still have the same problem as when I first got it -- maybe a little better.
I previously got the shinier (discontinued) version of this, but it started multi-clicking on me and I can't be bothered to add custom debounce patches to every computer I use.
My only real gripe (with both models) is that nothing obstructs the red light through where the scroll wheel is. I wish that weren't there, but otherwise the thing seems great so far.
