The pano thing is a mess. Fortunately something I've only used once, but even so, yes that's terrible and I WOULD expect better.
May I ask, have you purchased all of these from the same supplier? I think you may know where I'm going with that line of question, but it's not beyond reasonable to think it may be the suppliers you have used. Or maybe I just got lucky with mine.
Refurb Flymore package was DJI direct from their store - did the trade up turning in two iPhone 6 16gb and got $140 credit. Also got $30 credit posting in DJI forums for 18 months.
Second was an authorized DJI dealer where I could build my credit so to speak..
