It is a "fair" flashlight that is quite large (thick) and very easy to grasp in a single AA battery two-line formula. Grip is good, even if you fumble in your bag you will get it. I think that the whole is covered with rubber including the switch part of the push type and the waterproof · shock resistance performance is higher than the aluminum die-casting flashlight. It comes with a strap that just turns around your wrist, but its mounting part is also made of rubber thick enough and has a sense of security. Luminescence is an amber-like daylight color, it looks dark to the eyes used to the LED's white light, but it is a highly direct light with no glare (direct viewing is impossible). DURACELL, made in China, dry batteries are not included. Since the bulb is 2.2v 0.5A item, people who use it often will be able to use rechargeable batteries more cheaply. Alkali slightly increases the light intensity, but the color does not change. Well, in warm weather you worry that rubber will not melt, Well, at this price if you do not say much about the function, do not hesitate to say one thing carelessly whether you can throw in a tool box.
