Aldi Workzone tap reseating tool - is it rubbish? Test and review

A quick demonstration of a $10 Aldi Workzone tap reseating / re-lapping tool. These come on sale a few times a year. The quality of this one is adequate for occasional DIY tap re-lapping / re-seating jobs. Certainly much cheaper that a tap replacement. These taps have not been resurfaced for 39 years!
