Well, firstly the camera is tiny and only for everyday use, slightly larger than a standard matchbox. In terms of quality, I think this (and all other similar cameras) only gives around 720p quality when shooting in 4K. Requires a micro SD card up to 64GB. There are 4 buttons, one up and one down, a power button and an OK button. Pretty easy to use, picks up sound and is of decent quality. Made in CHINA, nowhere in the manual or product does it say "Made in China", but once you read the poorly written instruction manual you can find out. I receive CHOPPY videos in 4K resolution. at 1080p I'll probably get 720p type images. I haven't tried slow motion yet. Overall build quality is decent, but image quality leaves a lot to be desired. Mine shows some kind of choppy video on the recording, I think I'll be returning this product.
