Nice find! Here is another link for the same gimbal in US$ http://www.goodluckbuy.com/beholder-handheld-3-axis-gimbal-stabilizer-ildc-brushless-gimbal-for-gh4-gh4-nex-sony-a7-bmpcc-.html
It got qr plate design which is a nice bonus, but looks like all 3 axis is fixed and non-tunable, that could really limit what setup it can use.
Another brand enters the market

Found a user comment and some video on the J69:
because there seems to be no in-depth information from a named manufacturer - what about a manual, test samples etc.?
Buy one, make them :-) If you will wait - nothing will happen.
This "J69" looks interesting - I like that it at least has replaceable standard batteries.
I'm somewhat sceptic, though, because there seems to be no in-depth information from a named manufacturer - what about a manual, test samples etc.?
