I don't know how the product called that them is "the 1#".. maybe for market interesting. Not bad if it's really the 1#, but how if the others similar products also claim that the 1# too...

No Matter at all, It's really helpful for everyone get the data for their project use the drone. All terrain drones.. it sounds the main point that offers. If the product said that's the "all terrain drones" maybe you make wrong explanation in this part Can't Can’t go almost everywhere except underwater !
