Lillian, do you know who he is? The best sales representative I’ve ever dealt with. One of the best companies I’ve ever bought from. High-quality, unique tools—and this isn’t the first time I’ve bought from them. Fast response and communication. Shipping and packaging are the best I’ve ever seen—top-notch. This wasn’t the first time I’ve bought from them, and it won’t be the last. I’m writing this review with complete confidence.

Arrived quickly, well packaged, and feels sturdy. Works well. Immediately identified a leak from the throttle body. Very useful tool. Doesn’t come with oil though – you need to order that separately.

I’ve struggled with EVAP leaks for months until I got this AUTOOL smoke detector. Setup is a breeze, and smoke starts in seconds. The external gauges take the guesswork out of testing—I can see exactly if there’s a leak. No extra air pump needed, which saves time and money. It’s small, lightweight, and easy to store, plus the included adapters fit all my vehicles. The safety features are top-notch, and it works on my car, motorcycle, and ATV. If you need to find leaks quickly, this is the tool to buy!

Works really well. Unit uses fluid like baby oil to produce smoke. I’ve used it a few times already. Both to find leaks on the intake side and also the exhaust side. For the exhaust side, I really like the inflatable airbag you pressurize. Stick it in the tail pipe, pump it up until it inflates to the size of the tailpipe and there is no more air gapes between them, then pump the exhaust full of smoke to find your exhaust leak. Does what it’s supposed to do. Don’t know if it would last in a shop where it would get used constantly but great cost effective alternative for DIY’s.

It helped me a lot to detect the vacuum leak; I had been looking for it for over a week.

This little device is fantastic—small, practical, and high-quality. I’d had a problem with my EcoSport for a couple of years, and after using a scanner that led me to replace a bunch of sensors, this little machine diagnosed it in minutes. 1. It indicated a vacuum leak that I could never detect with the naked eye (I’d already tried using cigarette smoke). 2. An EGR valve that only malfunctioned at high speeds (not at idle), making it undetectable when the vehicle was in park. I highly recommend it.

Schnelle Lieferung. Super Teil. Hat direkt seinen Zweck erfüllt und mir somit definitiv etliche hunderte Euro in der Werkstatt gespart. Nach Verdacht auf Falschluft hat es sich bestätigt. Der Schlauch von der Kurbelgehäuseentlüftung hate sich unter der Anaugbrücke gelöst. Dieses Gerät ist ein absoluter Muss für jeden der selbst Schraubt.

The quality is very good, it is worth buying, it smokes quickly, I will buy other products again

Between SDT103 and SDT203, I chose SDT203. SDT203 is better, with a built-in air pump. Because SDT103 does not have a built-in air pump, I need an air compressor, but I don’t have an air compressor, so I chose SDT203

Use baby oil, very convenient to use, very good product, worth recommending
