Pros
Portable folding drone with carrying case for drone and its accessories.
Includes a lighted display case that also serves as its controller/transmitter.
Weighs only 76 grams with battery. Does not require registration in most countries.
Includes an optical flow system to help mitigate the drone from wandering in hover.
3.7V 1800 mah battery provides up to 20 minutes flight time per charge (I got 6 1/2 minutes indoors at low rate).
Advanced flight modes include optical flow, altitude hold, headless mode, flips, and flight path (via app only).
Camera can take and record interpolated (electronically enlarged) 2048 x 1080p @ 20fps video, and interpolated 8K still photos (video frame grabs) directly to your phone via WiFi. Camera also includes remote up down lens tilt control via the remote controller.
Uses the "KY UFO" app available on Google Play here https://bit.ly/KY-UFO and the Apple App Store here http://bit.ly/3JpgU74. App uses common 2.4 Ghz WiFi, which is available on most phones.
Cons
Brushed motor drone. Its motors will eventually fail with time.
Optical flow system can drift after takeoff or after maneuvering flight. But it will eventually recover to hover the drone if the pilot first manually controls it to hover.
The camera is not very good, and is not 8K as advertised (quality appears to be around 720p or less). Again, this is mainly meant as a beginner's learn to fly drone.
Battery appears physically much smaller than expected for an 1800 mah battery, and only provided 6 1/2 minutes flight time at low rate flying (vice advertised 20 minutes).
