Bought a $300 smoke machine 3 years ago, and it has paid for itself maybe 20 times
I was chasing an intermittent evap leak on a Camry and the thing found it in 10 minutes, after two days of me guessing. Every guy in my bay laughed when I brought it in, but last week the same guys were borrowing it for a Charger with a mystery misfire. What tool did you buy that everybody mocked until they needed it?
