I bought this box for my father to build a house. He went underground and when he started on the walls the trigger (plastic) broke into pieces. I called Bostitch direct and they sent a replacement free of charge, but there's no way the trigger should have fallen apart after two weeks of use. Ridiculous. I have since replaced the trigger with an alternative trigger (7 days delivery time!). while it works fine. hope it lasts The rest of the gun works great. No jamming and shoots well.
