A:Answer I crashed 3 times first day, there is no sensors on the top and the two sides, everywhere else its good. My drone crashed into a tree when I gave it the command to return home, it went straight up into a tree. The other two times it crashed into the side of my house using the follow me and active track features. Overall the drone is still great, even with the crashes the drone is in perfect condition, and you wont have this issue flying in an open space. I also have the DJI insurance that covers 2 replacements so I can fly the drone anywhere with peace of mind.
