That is one very expensive wrench.
Bought one-- used it once--- it marked up my polished spinners so much it is now very thick in dust on the shelf.
Went back to my 5lb. deadblow hammer works great, you soon learn to recognize the proper THUNK when they are tight enough.
As mentioned before 1 whack per ear does it & if you miss & hit the rim--no damage done, a little Flitz on a cloth & the black mark is gone.
I have never missed the intended ear, I will frequently catch the rim on the way in on the rears only.
This may not be suffiently tight for someone racing, but for hard streeting
has worked fine for me
