Arctic Hayes 333113 1 x Pen Kit with 3 Smoke Sticks, Test Slight Air-Movement, Gas Mandatory CO Spillage Checks of Boiler/Case Sills, Orange

worked well for doing leak test with my Milwaukee blower motor

Glad I found this reasonably priced, as I have seen others go for much more. Pretty basic tool, but invaluable. Get you one if you're trying to find problems with airflow. I'm in HVACR and this helped me to properly diagnose airflow problems and show the issue visually for proof. Recommend.

Does what it should.

Worked great

They make enough smoke to track the air movements. I used it to test exhaust hoods and they worked fine.

And when I’m out of smoke sticks I wouldn’t be shocked to learn I can’t buy them anymore. So it works well but in prob wouldn’t buy it again.

I’ve been finding all sorts of uses for this. I ritually it was to test hvac duct work but I find myself using it to demonstrate air intrusion as well as even finding vacuum leaks on a motorcycle. First burn doesn’t work well so light it before you need it and get a good char. After that it works well. Very little odor, most people don’t even know I lit something.

The boss love to see the super low air movement leaks from air ducts, and this pin does that.
