Is the 4K video real 4K?

It records files at 3840x2160, but the tiny sensor and lens cannot resolve true 4K detail. Expect footage that looks closer to upscaled 1080p, best in bright light.

Does it come with a memory card?

Yes, a 16 GB TF (microSD) card is included. That holds a limited amount of 4K footage, so a larger card is worth adding for longer recording.

How long can it record on a charge?

Battery life is short, as with most cameras this size. Expect well under an hour of continuous 4K recording, less in cold conditions.

Can I use it as a dashcam or action cam?

It can record in a car or on a bike, but there is no stabilization and no mounting system beyond the keychain. A dedicated action cam handles vibration and mounting far better.

Does it record sound?

Yes, it captures audio through a small built-in microphone. Sound quality is basic and picks up wind and handling noise.

Is it good for serious video work?

No. It suits quick, casual clips. For interviews, vlogs or anything you will edit and publish, a phone or a dedicated camera gives much better image quality and control.
