Worked great helped me find evap leak. Great tool for the price. Easy to use.

Funciona muy bien, solamente es que ocupa un compresor aparte para aventar el humo y comprar aparte el aceite especial

It's great little machine I've used it three times now and had success all three times

I am a master tech our smoke machine ended up breaking so I got this and so far have been very impressed by it, works great, and seems to be faster then some of the higher quality ones I have used

This machine is a must-have for finding vacuum leaks. I spent weeks trying to find leaks by listening and spraying various fluids etc and could not find all of the leaks. This machine found hard-to-find leaks that I would have never discovered within minutes. It does everything that the expensive machines do at a fraction of the price. I can't speak for longevity or durability because just received the item, but it appears to be a solid, quality build. It is compact and can be used on basically any size vacuum hose or the larger air intake opening. You will need shop air for it to operate with standard industrial couplings. Any sized air compressor will work since it only requires around 5 psi input pressure. It has its own internal regulator so you don't have to regulate it with your compressor, although I would assume you wouldn't want to run too much pressure into it because maybe it would damage it over time. I set my compressor at its lowest setting which is around 5-10 psi. If you don't have a compressor and don't want to invest in one, this brand and other brands sell machines that cost a little more and generate their own air. Either way still much cheaper than the expensive machines.
