ONE Air Leak Detection - Handheld Smoke Stick - Draft Detector Puffer Fog Pen Machine Kit

This smoke pen has been an incredibly useful tool for understanding air movement in my home, particularly for diagnosing radon mitigation effectiveness. It produces a steady, visible stream of smoke that makes it easy to track airflow patterns around vents, doors, and basement areas. The build quality is solid, and after months of use, it still performs just as well as when I first got it. It’s compact, easy to handle, and doesn’t create any mess or strong odors. Unlike DIY alternatives, this pen provides a controlled and consistent smoke output, making it much more reliable for precise testing. For the price, it’s an excellent value. Whether you're troubleshooting radon mitigation, HVAC efficiency, or general ventilation issues, this smoke pen is a must-have tool. Highly recommended for its durability, ease of use, and affordability!

I have had two of these little black beauties. The first one I bought over five years ago. It only half way worked, with minimal - and I do mean minimal - smoke. I think I tossed it out sometime back. I needed another generator, so against my better judgement, I bought another one. It's the same problems. Little "whisps" of smoke, if any at all. It is not easy to fill and when doing so, it leaks the sticky oil all over. In my opinion, this unit is a cheap piece of junk from ... you know where.

Works fairly well. Difficult to secure plug in fill port, so leaks at times. Pump trigger is inconsistent, large puff at times and less at times. Strength of batteries may have some affect on amount of smoke. I may need to learn to work it. Product met my needs.

The price is a bit high, but the device produces smoke very quickly and works exactly as intended. It helps detect air leaks efficiently and gets the job done. Overall, it meets the expectations and performs well.

Bought 3 one worked great, one worked for a while then quit working then would start again, one never worked at all. Have bought these before and definitely not a long term investment product. Buy what you need for a job (with spares) and you'll be ok. Wouldn't plan on keeping them around for multiple jobs, or if you do test them in advance. Glad I bought 3 but didn't expect to only have 1.5...

When it works it works well. The design needs refinement as fluid can easily leak into other parts of the unit, rendering it useless. The method of siphoning fluid from the unit after use is cumbersome and not always effective either

I got this to help identify drafts around windows, doors, walls…anything! It produces a white smoke which is easy to see with the green light it emits. It took a few tries to understand how to use it since directions were not the best. Lightly pull the button (not the pressure trigger thing) and it will begin to smoke. Pulling the trigger will create puffs or a lot of smoke at once but will also deplete the smoke so will momentarily need to create more. Overall it does exactly what I wanted it to for a fair price.

Bought it to test a shop dust collection system. I gave up after 15 minutes trying to get this thing working consistently. I buy a tool to perform a task, not to fight with me. The smoke stream is inconsistent at best, at worse there is no smoke and only sore fingers. It's just an awfully designed and sloppily manufactured piece of junk. Straight to the trash bin where it belongs. Bought the Artic Pen to replace this thing. It's not pretentious and it is reliable at the same price.
