I had a pair with the replaceable tips, used them for decades with no problems, not even with them rotating, as the shanks were hex, and the jaws were grooved. Bought an extra box of tips a few years back, no tool in sight. Only disappointed once a few years back, they would not go small enough for a project.
Bought a few different types recently at GS over the past few years for a buck each, no problems, seen more snap rings the past few years than in the previous 30, and ready for all of them, so far.
