Impressed - paid for itself already
I have now used this smoke machine to locate boost leaks on 2 of my vehicles. It has successfully located splits in boost pipes on both occasions so has already paid for itself. It’s reliable and easy to use.

Works like a dream produces lots of smoke within minutes of starting machine

Seems perfect for occasional use
This performs well and is the more basic version. More money would buy the same unit with additional features. We bought it for one specific job but can see it being used in the future now it's here. Perfect for the home mechanic with an elusive leak issue.

Works perfectly
I needed to check to find where I was losing coolant from. Usually it’s obvious, but the pipe I suspected was such a massive job to change (remove intake manifold) I wanted to be 100%! This did the job perfectly! This was the cheapest I could find. Which is another bonus, because it’s not exactly a tool a diyer is going to need everyday

Needed one to check for leaks and didn't want to spend a lot of money. This one is cheap and with a $10 bottle of fluid it works great! Plenty of pressure and smoke. Feels a little cheap but seems tough. Nice and small with a big fluid reservoir. And the instructions are somewhat helpful.

Muy útil tiene su compresor incluido y arroja humo a presión suficiente para revisar varios tipos de fugas desde vacíos en admisión y escape así como fugas de aceite y sistema de enfriamiento

Très utile et pratique. Fonctionne sur batterie 12V. Elle m'a permis de trouver des fuites a l'admission de mon véhicule et des fuites sur un circuit d'huile. Je recommande sans hésiter. Fonctionne avec de l'huile pour bébé. 👍
