I did hear about it! The funny thing is I ordered one of these on eBay right before DJI released theirs. But the one on eBay never shipped and I got tired of waiting so I went to pick this one up instead.
I really agree with you, I don't think the one from DJI will do any better than this. As a matter of fact, DJI seems to be behind a lot. Even the Zhiyun Crane for phones already had vertical mounting capabilities..
I do however, want that new Mavic Air from DJI :D
