Trackballs

For several years now I've been using the Kensington K72337US ORBIT TRACKBALL  its a great mouse to use with a gel wrist pad. This has kept my arm off the desk, and and reduced painfu; hand issues I had been experiencing. Ive been programming all day every day for years now, and for a while I was really having a hard time with mousing and clicking and scrolling. The wrist pad and scroll wheel change the lean angle and the fingers used to do the tasks, this changing the repetitive motion issues. The mouse today, after about 5 years has stopped clicking. So I have to say its a darn good mouse. Im looking at buying another and they are back ordered so I'll have to use a traditional mouse for a few weeks. We'll see how that goes.

Here is a YouTube video of the mouse I found
