1st time: The Torx 5 fit rather bad and had just enough for its purpose. He had too much play.
2nd time: 1.5 slot at a slightly tightened screw. No Problem.
3rd time: 2.5 slot on a fixed screw. The first time ever in my life, the tide has turned a screwdriver. I know that something breaks it when the load is too large. But that?
My previous conclusion: That was to be expected for the price with the fit and would not let the rating fall below four stars. But the soft material from which the bits are apparently manufactured not going! Such a thing is not even happened to me with the cheap freebie-sets that I had laying around over the years with me.
So: buy only the very light claim. Fixed screws or things that really need precision, are too much for this set. Too bad that was just saved where the cheaper sets not save otherwise.

Slot 2 has not just survived the first use of a fixed screw. And again another Billigset has had no problems with.
