An indispensable traveling utensil, whether in the dark foggy night or on a bicycle, this headlamp I have always with me when I pursue one of my hobbies. If you read through the operating instructions, the battery installation is a breeze. The headband once set correctly (not too tight), fits well the next time after a downpour as adjusted. For anyone who according to his needs adjustable light angle and three brightness levels this high quality product complete. Much to Tell!
