I've been using the AutoLine Pro EVAP Smoke Machine for a few months now, and it's completely changed how I approach vacuum and EVAP system leaks. The solid metal construction gives it a premium feel—this isn't some flimsy tool that'll break after a few uses.

What really impressed me was how quickly it produces thick smoke. Within two minutes of setup, my garage looked like a fog machine convention. Unlike cheaper alternatives, this thing pumps out serious volume—I found a hidden intake leak in under 15 seconds that I'd been chasing for weeks.

The ceramic heating coil works great, though I did have to replace the wick after several uses (Autoline's customer service sent a free replacement immediately). Pro tip: keep the original fluid bottle cap—the folding nozzle isn't the most durable part.

While it doesn't come with many adapters, the tapered nozzle fits most hoses perfectly. I've used it on everything from turbo systems to EGR valves with consistent results. At this price point compared to professional-grade units, it's an absolute steal for home mechanics.

The only minor complaint? The smoke fluid has a strong odor—definitely use this in a well-ventilated space. But considering how much money I've saved diagnosing issues myself instead of paying shop rates, that's a small tradeoff.
