I really like this mouse for trading. It is the Gyration wireless mouse. The thing that makes this mouse different is that you can use it on the table like a regular mouse, but you can also use it in the air.
There is a trigger-like button on the mouse. When I click that button and move my hand, that moves the mouse based on the 3 dimensional movements of my hand. This allows me to use more natural arm positions to move the mouse. It cuts down on the stress to my wrist and lets me enter and exit trades while sitting back in my chair.
The hand movement to mouse movement translation is excellent and I am never worried about clicking the wrong thing on the screen.
There are also three additional buttons below the standard left button, right button and scroll wheel. These additional buttons are programmable and I have set them to do browser functions when I am surfing the internet: navigate back, navigate forward and refresh.
The mouse has a rechargeable battery that can be removed and replaced, if necessary. There is a charging base that is included with the set which allows me to easily charge the battery by just placing it on the base.
I bought the keyboard/mouse set, so the mouse also comes with a wireless keyboard. The keyboard layout isn't the best, but it is very compact and I like that.
It runs on 4 AAA batteries. I use rechargeable batteries that last a few months before I have to charge them again.
My only complaint with the keyboard is that I cannot tell if the caps lock is on because there is no indicator light. I have learned to live with it though, I guess it prolongs the battery life.
I have been using this keyboard/mouse combo for about 3 years now and I really like it. Click here to check out the details.
