Hello Alls, this is 1st time to check and join here. As a programmer design and tester, I am looking for something new to try.

Not sure if this is the right section, moderators, please move if not.
I picked up a tool sales catalogue from Kingchrome that had a new item for me, a brake fluid tester for just under $50.
I checked the item on Ebay & found I could buy, what looked identical to the Kingchrome tester...
