I hesitated a long time before buying this product, or other products "made in china" at equivalent power. I chose this model 2 LEDs for greater opening angle. Level finish, I was expecting a risky result ... is nothing wrong this is neat and the battery does not give the impression of wanting to explode any moment. I'm outputs with 3/4, approx 1hr use during the level indicator (3 green LEDs) has still not moved (with charge made by the manufacturer) having used primarily to small and medium power. Maybe 20min has strong power. If you are looking for power, like me, to quietly make winter trips when night falls too fast. This product is for you! I was amazed by its power. I expected the powerful, but not at this point! Certainly equivalent product Magicshine but 100 less.
