Just got my YI 4K, this little thing is stunning!

Just a picture if there's someone curious

First impression is very good! Have yet to update the firmware (currently running the "ancient" 1.0.7), but it is smooth and usable. Camera itself looks sturdy and well built.

I also got a couple of additional batteries with an additional dual charger; they are from the BatMax company but it looks like they work fine with the YI 4K. Have not tested the waterproof case yet.

Still have to receive my the MicroSD card I will use with this camera, I got a UHS-1, hopefully will be enough in terms of read/write speeds!

U3 cards are generally preferred for real 4k, may depend on the bitrate though, not sure how high these go

Already got a Nice UHS-3, 64GB SanDisk. Problem solved, let's hope I'll receive it soon
