Firefighting is definitely one of the very practical uses of a drone. I think it is quite impressive this drone, how stable it looks, with what amount of water weight and pressure it has to deal with. I can't find a negative on this one, not without having one to play and test with myself. Ok ok, a down side is maybe the water hose which decreases the flexibility in movements and reach, but then again, without the water hose, no firefighting drone unless a whole helicopter is build. Conclusion: looks very solid without any negative thoughts about this product.
