serial tool abuser and the only thing ive broken was a 1 foot extension bar …. i was using it on an electric 450nm impact driver ( its not an impact driver approved tool)
and it didnt even really break – the socket retaining ball bearing on the end came off…. but it also removed the stubborn bugger bolt i couldnt get into with anything else and get purchase and weight on it 😀
would buy again – recently bought the 49.99 set of spanners that go up to 34mm as i needed a 28 and 32mm ring spanner and again they are holding up well – they are not advanced profesional but they havnt broken yet – and i was swinging hard on the 34 removing suspension bolts that havnt been touched in 15 years.
