I had 3 LED Lenser H7 headlamps and they rocked, but there were problems with the switches on all 3. I sent them in for warranty repair, and I received 3 new Coast HL7 headlamps back. complete with batteries. Let me tell you, these things are BRIGHT and there is a definite improvement on the focusing function. Coast takes their products and their guarantees seriously, and I will not hesitate to buy Coast products in the future. Thanks, you guys, especially the staff in the warranty repair department.
