Title: Not Good! My Hand goes to sleep!
Review: I have trackballs on every computer in the house. They aren't optical like this one, but I wish they were. No more cleaning!But I can't for the life of me operate this one like the others. I am used to the index finger moving the ball and the thumb doing the clicking, so I am constantly fighting this thing! Plus my thumb doesn't have the range of motion that my finger does, so it isn't as easy or as quick to move as the other kind!The part that really gets me though, is that my little finger and ring finger goes to sleep and then I get pins and needles!Maybe you can get used to it, but I won't! Will be replacing this thing ASAP.
