Treat it smoothly and it should last you a long time.
You have to be very careful (as in treat it delicately). Given its small millimetric size teeth, they are more likely to break faster than say size #6. For obvious reasons, treat it with care. This is the only 'defect' i see in this but it's not really their fault (maybe making the plastic of harder/tougher material?) but overall this is a great buy. It fit wireless Wahl 79141 Battery Clipper perfectly.
