The build quality is fine and everything makes a stable impression. A drop of oil on the threads does not hurt before you start to screw securely.
Very important: You need a 24er key.
I can only recommend everyone to go up a 24er ratchet wrench (if you have not yet), because it facilitates the work very.
As one can see in the picture, you get a normal ratchet here not far and for an impact wrench, the tensioner is allegedly not suitable, but would also bring nothing anyway.
Overall, for the money absolutely great. I do not know how to get there with a clear conscience can still buy the 15 China-parts themselves.
