The torque range of this key is 10-80 which allows a precise clamping. The majority of dynamo key sold within 50 have an amplitude of 30-210, which is not very precise. So in terms of accuracy that's perfect.
The tip is 3/8 therefore more easily adaptable to 1/2 or 1/4 sleeves.
With a length of about 40cm it offers good grip and helps tighten without forcing.
No complaints about this.
