Problem:Overall better that than my old logitech trackball. I have been using trackball for over 7 years and prefer it over any mouse.<br />This newer model is more convenient because of the small USB wireless connection. I can now leave the USB in the dongle in the port. My old system had a 18&#34; wire from the USB port to the wireless controller.<br /><br />The only thing I had to do with the unit was adjust the pointer speed. The new ball rolled so much easier than my old one. I guess I didn't realize how old and tired the old unit was getting.<br /><br />This unit also has improved battery life. Mainly due to electronics puts the unit to sleep after no activity periods. It wakes up immediately and user doen't have any idea that the unit was asleep. Aditionally, there is an on/off switch that you can use for storing for travel. Old units I have had, required you to remove the battery to protect if from drain by accidental operation during travel storage.<br /><br />This unit has worked perfectly out of the box and has been a great purchase.
