Very good quality, better than other brands I have used before. This smoke leak detector has a built-in air pump. It is small and easy to carry. I can use it easily. The smoke effect is good. A lot of smoke is produced in 20 seconds. I use baby oil.

Pipe inspection is very useful. Although it is very small, it has a built-in air pump, so it can be used for inspection at any time without the need for an additional air source, providing greater convenience. I am very satisfied with it.

The smoker is a great product, portable and lightweight, I used the Johnson’s baby oil they recommended to go with it, it’s an amazing combo, but the smoke comes out very well, I have a repair tool sales store, can I resell it please? Please contact me, thanks!
I was pleasantly surprised, the quality is totally different from other brands, very good, I like it very much, and it quickly helped me find the leak, I used baby oil, 15ml each time
This thing works just as well as a larger machine, and I was surprised judging by how tiny it is. Works great for smoking fuel tanks and even for engine vacuum leaks.
