Brilliant Product
Very simple to use and for me I thought very accurate. Slightest hint of exhaust fumes and the fluid turns a bright yellow immediately.My car passed the test, The fluid didn't change colour at all so just to be sure I held the sniffer about a meter from my exhaust on my driveway and a couple of sniffs and bam straight to yellow. Spot on.
