I cant fault snap on at all.all the stuff I buy is snap on because its easy to get hold of and when things brake theyreplace them with no questions asked.i snaped a punch in half last week using it to stop somthing turning whylst I undone it.gave it back to the local dealer and he replaced it.you could see that it didnt brake by hitting it and it was abused but still replaced it the quality of the tools isnt as good as they use to be but they have a warrenty so that dosnt matter
