Summary: This is a replacement for one I have had for many years. A must have since I have arthritis in my fingers, hand, wrist, arm shoulders, and neck. I love it, and can not imagine my life without a good trackball
Summary: I have had trackballs in the past and always was disappointed. I thought technology would have grown to make them optical. Still requires a clean ball and there is no software to change button behavior. As long as the ball is clean it is fine.
iOne Libra 90 PU Ergonomic Trackball - A trashball
14 June 2013
Summary: Beautiful photo, from the box to the desk ... to trash. How can be designed an awful trackball that is so ... no words to describe it because the ball did not work to the left side, no sensitive enough to move the cursor to an exact place in the screen, it is like working with a "drunk" cursor.
Summary: Not a bad item. Bought it for a friend as a gift; she didn't like the ball movement; thought it was too tight; returned it; no hassles; seller very accommodating; very prompt on handling the return; didn't care for the 15% restocking fee; will read the fine print more closely the next time.
Summary: I got one of these off of ebay for less then 20 dollars shipped. While I only have had it for one day it doesn't seem to be such a bad mouse. The trackball rolls on metal rollers which is nice as they will last for awhile. I am running it under linux and am using a 24 inch screen.
Summary: The iOne 3 Large Button USB PS/2 Trackball Mouse is not as advertised ! IT'S CHEAP GARBAGE ! They claim 6400 dpi but there is NO WAY ! The tracking speed is far too slow even set at the highest setting and the mechanical tracking is not accurate .
