Holy Stone HS440G
Score: 76/100Rankings
The Holy Stone HS440G offers a 4K camera, GPS-based navigation and brushless motors in a sub-250 g foldable frame. Its battery life of 23 minutes and modest wind resistance are trade-offs for the advanced features. Best suited for beginners who want GPS stability without registration.
The DEERC D20 is a lightweight, beginner-friendly mini drone featuring a 720p FPV camera and robust propeller guards. Its short 10-minute per-battery flight time, limited 40 m range, and wind sensitivity restrict outdoor performance. Ideal for kids and new pilots seeking an affordable, easy-to-fly indoor drone.

They also commend the brushless motors for durability, while noting the drone's lightweight nature limits wind resistance and long-range performance.
Everyday users consistently praise the HS440G for its portability, easy-to-use controls, and clear 4K footage, appreciating the no-registration advantage.
