Works great. Did what it promised at a very reasonable price.

Once I took a trip to the store to grab the correct quick connect fitting for the air supply, it worked perfectly. Threads are standard which makes it all the more confusing on why they selected this random fitting. Construction is better than you’d expect of the price.

This is quite possibly my new favorite tool for my car. I was previously getting burned (literally) when manually bleeding air out of my coolant system (Audi V6 3.0, notorious for air pockets). I don't know how I'd ever go back to just a funnel (even one of those fancy tall ones which do help with bleeding).That being said, the tool has a few quirks that you need to be aware of before using it:I had to cut off the rubber sealant stopper at the bottom so it would fit in my coolant tank, as there was an obstruction that didn't allow it to go all the way down. Easy to do with a knife, and sealed properly after that.The second time I used the tool, on the same car, I couldn't get it to pull a vacuum at all, and it would just hover around -10inHg and then lose pressure. I noticed that when I opened the valve, a little liquid shot out, probably just being pulled from the reservoir. No matter what I set my air compressor pressure to, it wouldn't pull the vacuum. After thinking for a little while, observing that the outlet on the tool was cold, I finally got to put my aviation knowledge to good use.The vacuum tool works by using a venturi, which squeezes high velocity/pressure air through a small opening, which will in turn create a vacuum on the other side, and that draws air out of the cooling system. Let's go back to high school chemistry and the inert gas law (PV=nRT). The venturi reduces the pressure of the air (vacuum), as well as lowering the volume through the venturi. If pressure and volume go down, and we don't reduce the number of air molecules, what else has to go down? TEMPERATURE! What happens when you have a little bit of liquid in the venturi, and the temperature goes down? IT ICES UP AND CLOGS!What component on a small airplane also has a venturi, and uses a heater to break up ice? A carburetor and carb heat!After applying some heat to the tool and letting things melt, it was back working, and found probably 2L of air pockets that previously could not be bled out of the system with the bleed screws.
