I bought the spark fly-more combo from dji several months ago and have logged over 30 flights thus far. I was flying like all other times and1.) I was "GPS ready to go"
2.) There were no obstacles in between me and the drone.
3.) The drone was only 200 meters away
when all of a sudden my spark "loses transmission signal" as in the screen blacks out. Then i wait to regain an image, it never comes back, so I return home. Well, of course the drone flies past me and then lands into the ocean because by then the battery was so low that it had to do an emergency landing. It was recovered but is obviously no longer functioning.

Just BE WARNED. The spark, or atleast mine, is not as reliable as professional grade drones and cannot be trusted over water or anymore than 1/4 of a mile from you. I'm extremely disappointed with the software of this drone, and having read through other posts, I don't feel like customer service with even give a look to the claim I submitted
