good for the price

Machine is lightweight and worked perfectly to find a vacuum leak. Doesn't put out a crazy amount of smoke but puts out enough to get the job done with ease. It doesn't come with any liquid to make smoke but they were specific on what liquid you need (Johnson's baby oil, pink label) and it doesn't take much to fill the smoker. Overall it's a great machine for the price.

Had a Ford Taurus that would not idle without dying. Instead of throwing parts at the emissions control system, I used this to find I had a vacuum leak in the intake system causing the engine to run too lean. Great piece of equipment, easy to use, and eliminates throwing parts at the problem. Wished I could have gotten this piece of equipment years ago. Ending up in the shop would probably have cost me 600 - 800 dollars to have it fixed. I was just missing a vacuum plug on an unused port behind the engine that I couldn't see without the smoke.

This smoke machine leak detector worked like a charm on my 1998 Silverado! I had been struggling to pinpoint a vacuum leak that was causing my truck to idle rough and guzzle gas. After connecting it to the vacuum system, the machine filled the pipes with smoke, and within minutes, I located the leak. The built-in air pump makes it so easy to use, and it’s compact enough to store without taking up much space. It's definitely a lifesaver and saved me a trip to the mechanic. Highly recommend this for any DIY mechanic!

Very easy to use
This was exactly what I needed for my old car. It's very easy to use and works really well to identify leaks. It smokes up easily without leaving behind a strong scent.
