I have it for about 2 months. It has impressive brightness, both in the central focused and in the diffuse perimeter. It is great for any work inside or outside the house. As for durability, it is too early to say. Its construction seems good. It has 2 cheap quality 18650 batteries that do not last as long as one would expect. I will replace them with better quality ones. I think 200m is excessive for distance. However, it has impressive performance at 100-150m. For its price, it seems like an excellent purchase
