I must be purchased 4 or 5 because almost every time I make "demonstration" with friends ... they want one that I shall command (or they are controlled) and they never disappointed. Many are buying two or three (one per car and at home). Excellent power with a "real" lighting to more than 80m (and even benefit) at night in zoom mode, great lighting circle wide angle of about 3m to 4m away already. Night on a bicycle lamp lights as a car headlight smoothly. The holding duration is greater than 1 hour in full power (I have not tested longer continuous). The second battery doubles this course time and in an emergency you can use 3 AAA batteries. The car charger is a big plus for isolated locations. Anyway ... all good
