Own a few Lang Tools in toolbox, some just real China junk and some very decent. I have noticed though if you are purchasing Snap-on, some tools are re-branded as Lang Tools but Snap-on changes the name and brands as "Snap-on". Very cleaver in my opinion as a purchased a vacuum gauge from Snap-on and found the label behind says "Lang Tools". Looked up online and the same tool except the case was different color and model number were different. Returned to my Rep and purchased that one because of the price. I also noticed another review state this. Anyway about the tool, the tool comes in a small gray case. The case is small and doesn't fit the tool and the hose well but it works. Like it stated, some good tools Lang Tools makes and some bad tools. This appears to be a good tool. The quality is decent and seems to be accurate, i will not go through the whole process of explaining how it works. The tool comes with an extra adapter and detailed instructions on how to properly use it. I looked for other brands just don't like the setup, i like the two gauges design. This isn't a tool you will use all that often as a technician, i have used it roughly 3 times in a month and a half i have owned it. Nice tool to have and no to borrow but also not a necessary tool. I would totally recommend this as this a just a re-branded Snap-on for less the price.
