I got this to find a vaccum leak on a few vehicles I have been working on and it made it 10x faster! Smoke feature works great. I got the one with both gauges but haven't found an application where those are useful yet so I am unsure of if they're even worth getting or if they work really but for the price you can't go wrong.

This was the first time I've used a smoke tester and I didn't have any major issues. There are a few adapters in the kit that are not explained in the instructions but I was able to rig up what I needed. I used this on a 2006 PT Cruiser and was quickly able to see smoke come out. I recommend doing this inside or on a day with zero wind. A light breeze makes it very difficult to see the leak point. Note that some cars you need a bi-directional diagnostic tool to open the tank purge valve. I couldn't use the manual option because it's located on top of the tank and there is no way to access it without lowering the entire tank.
