Looks like a decent quality bit. As others have pointed out, the packaging is silly. All they have to do is wrap it in a piece of paper or styrofoam, but they just toss a precision instrument into a loose plastic tube to rattle until it arrives (mine was undamaged on arrival). The most important thing to know is that it will not fit the standard 1/2" router collet that most US routers have. The 1/2" milling collet is lightweight and even seems to tighten (you can't move it with your hands). However, when you turn on the tool, there is a lot of vibration, and unfortunately we even tried to cut off a little. The bit got stuck and we were only just able to avert a catastrophe. Well, that's all my fault, but if I can help someone else avoid this, great! You will need a 12mm ID collet, which is not easy to find. Just ordered one that hopefully fits, will try to update afterwards.
