Robust, but some flaws.
This flashlight may seem pretty ridiculous. The factory specifications seem absurd, in addition to the price. Well, those specifications are correct. This is a very bright flashlight. I can easily see where this light shines, even in the bright California sunlight. Since it's so small, it's easy to carry. I bring this wherever I go in case of emergencies. The only downside of this flashlight is that it eats up batteries quickly. Assuming the user is not using this 24/7, the batteries will have to be swapped every 4 months. At the end of the 4 month cycle, the light is still relatively bright, but obviously not as bright as when fresh batteries were installed. If one ran the batteries dry, it would probably take 5 months to kill a set of batteries.
