Good quality, fits into a total wrench, doesn't come out unless you want it to, and the tip locks in with one motion.

Relatively good. Its negative aspect is that if you put it on the Dewalt or Parkside impact driver, it falls off very easily. (For example, if you try to turn it downwards) It does not hold the male 1/2 inch base securely. It's a shame because as an adapter, it is very good.

Does not fit the 1/2 on the wrench and it pops out when rotating??? The safety does not come off, it gets stuck, in order to remove the 1/4 attachment??? Unless you are Tsouplenkob?? The 1 star is for the nice color! On the second day, I threw it away and got a Chinese one for 1.5 euros with perfect fit!
