Very nice and good tool !! Very effective, my tire dealer has the same and is delighted. This tool must be extremely dangerous given the number of pages devoted to security, (lol) by cons I had to call my one brain to make it work lol, because nothing in the user manual. The command is very convenient by bringing the couple and the direction of rotation. A nice burst of the machine is provided, but no description of the component parts. In short a purchase recommended, product quality, packaging, delivery speed, especially the barrel price. Bravo and thank you Amazon.
