I do not have the equipment to test it. It looks to be in good condition. See photos. The software is old, so there is a chance the disc does not work. However, if you send the trackball back to me, I will return your money.

Please see photos.
This is the only one I have.
I sometimes travel for work (where I sometimes find my treasures), so that is why I selected that it might take me 3 days to ship. If I am at home, I will ship ASAP.
Ships from Milwaukee, WI.
Thank you for considering the purchase! Your purchase really helps my family!
PLEASE! If there are issues, contact me and give me a chance to make it right before you leave bad response.If I can ship on the weekend, I will. However, open hours are limited at the post office, and there are some weekends where I am unable to ship. As a policy, does not count weekends as a business day.
