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.
