Over the last couple years the Lesco nozzles for the chemlawn gun are nothing but junk. If they aren't cracked between the holes when you get them all you have to do is touch the damn thing on the end and it cracks. The pattern sucks. Am lucky to get 1 good one out of 3 ordered. They are made so thin that a higher pressure would probably blow the whole end out of it. Anyone else having this problem?
