Very underwhelming. The camera solution they adopted is technologically inferior to the (much more common) dual wide/tele lens solution, since the former offers only some of the advantages of the latter (e.g. bokeh: yes, 2X optical zoom: no). And they gave that guy who retrofitted a headphone jack in the iPhone 7 a reason to come out with a new video.
