Whether it's worth the money to you depends on how well you fly and what you want to achieve.
Flying is secondary to me; I am
mainly interested in the film or pictures I can get. My "enjoyment' of flying is tempered by a large amount of fear, both of losing my investment, and the damage my drone could do if mishandled.
Litchi helps with both of those fears - I made a brief film about my growth in confidence that explains this (
