The YI 4K Action Camera from Xiaomi-backed YI Technology, which was launched in China back in May this year, is currently available for pre-order in the United Sates. Amazon has the device listed on its website.
As for price, the camera - which is available in black and white color options - carries a tag of $249. A bundle that includes the camera, a selfie stick, as well as a Bluetooth remote costs $279. Launch is set for July 12, which is tomorrow.
I think the SJCAM M20 is much more better than this.
I am in china , but i cannot find it on xiomi official website. This device and bicycle is not listed on their official website. Whats the story.
