Buy once, cry once.
Excellent, as you'd expect. They fit the screws I used well, but that applies only to the brand I used.

picked these up because of the reputation of Wera and they are legitimately great bits good for power screwdrivers and hand held tightening as well grip well and fit well wear so far seems very acceptable and I expect to get better than average life from them based on recent usage very happy

Broke first 2 bits in a half hour and threw the rest in the trash can to save myself further frustration. Worst bits I ever purchased. Extremely disappointed in a brand I had once trusted.
