I can't say enough great things about the Atom2! Radio connection stability, range and consistency are excellent along with video transfer bit rate. Flight control is fantastic with the response and settings you would expect from a comparable professional microdrone. Camera functionality also either out-performs or performs just as well. Battery life is fantastic and a comparable 40 minutes - what you would expect from other pro brands. The only functionality absent from this model by Potensic that you often see elsewhere is collision avoidance that being said, the subject tracking is stellar on the Atom2 and there's a nice preset selection of AI assisted camera shots. Potensic recently added p-log color format during a firmware update and there are now camera filters on the market specifically made to fit the Atom2 (there are also several camera filter brands that work with the Atom2's camera even if not stated outright). Fantastic drone for beginner or expert pilot!
