Professional reviewers and editors consistently praise the HS190 for its beginner-friendly altitude hold, ultra-easy one-key controls, and pocket-sized foldable design, calling it one of the easiest drones to fly. However, they also note significant drawbacks such as the very short 5-7 minute flight time, limited 30-meter range, and lack of a camera, which keep it from appealing to more advanced hobbyists.
Everyday users love how simple the controls are and enjoy the LED lights and flips, especially for indoor play with kids. The most common complaints revolve around the brief battery life, the single-battery packaging that forces long waits, occasional drift needing calibration, and the short operational range.

Professional reviewers describe the DEERC D20 as a fun, easy-to-fly mini drone that excels in sturdiness and value, highlighting its crash-resistant props, intuitive auto-takeoff/land, altitude hold, 720p FPV streaming, and the inclusion of two batteries for extended play, while noting the lack of onboard storage and modest range as minor drawbacks.
Everyday users love the D20 for its beginner-friendly operation, stable altitude hold, entertaining flips and lights, and the value of two batteries and a carrying case, but they commonly criticize the short flight time, wind sensitivity, occasional app connectivity issues, limited range, and the camera's performance in low light.
