I bought this in the summer and only used it to change my BMW wheels. Colouring, metal quality, knurling depth - these are all excellent properties. Needless to say, these tools are essential in your kit to change the wheels on your Bimmer. This is both my first BMW and my first suspension tool, it made changing a wheel super easy. Even without this tool, you would have to put a lot of effort and creativity into a very simple maintenance task. Great Stillman product. Many Thanks.
