You did get a bargain. I think I paid a tenner for mine about 20 years ago. It is a pretty good in-circuit tester (rather better than most). I hope you got the 2 leads (one for small signal transistors with a strange double spike probe on the end, the other for power transistors with a pair of croc-clips) and the (green) probe to connect to the base of the transistor under test.
