The ENTIRE trackball assembly is incredibly durable.........no problems with my curve and/or my Son's Pearl...........even after my Son's 9000+ text messages a month.........it holds up well.......the BB's are remarkably durable devices.

The trackball is quite durable, it just needs some routine maintenance on occasion to remove the pocket lint that always seems to work it's way under the ball assembly.
