Aren't drones illegal? Well my friends if they were, they wouldn't be sold as consumer products. However drones are not your ordinary toys and if flown professionally involves applying for a license as well.Dji drones are equipped with obstacle sensing capabilities thus allowing you to dodge or sense obstacles instead of bumping into them. Fun fact if you've not operated a drone, Dji drones have the capability of sensing the location you're flying in, it then alerts you if its near a restricted airspace such as a government building or a landmark, by stating you're in a no fly zone on your controller. In addition to that, if your battery does die, your drone has the capability of coming back from where it did take off. Disclaimer alert , I'm talking from my experience after flying Dji's Mavic Air and Mavic 2 series.However the game changes when you travel with your drone, its important you lookup the countries drone laws (Available on Google). Convinced enough of buying a drone? I mean you should,it all depends on your requirements but I'd definitely recommend the Mavic Air, however there are talks of Dji releasing the Mavic mini 4k drone which is a smaller version to the current mavic lineup, its something that I'm waiting for to take with me on my travels.
