Hi Guy's
I bought 3in blue transparent trackball from Starburst Coin Machines, in person for 100$CAN. Box was open and then re-taped when I got it. Didn't noticed till I used blue LED to lite it up there was nasty scratch from razor blade across it. Gave them a call and and they apologized and told me to send it back for replacment.....cool. Now second one came back with even more scratches, not as deep but more than few. Plus there is also 3 marks I guess from shaft 1/4 in long and 1/16 wide.
