Size, I like the heftier size over MA2, easier line of site flying.
Love the camera.
Prefer the Go 4 App
Refurbished felt exactly like new. Great way to save money. Do again in a heartbeat.
I liked the RC except for the issues below (screen and extra custom buttons).
The Controller mounting of iPhone X with (or without) a fairly minimal case was very frustrating.
I hate the charge plug on the side of the RC (it's fragile as folks know and constantly having to pull it out for charging makes it worse) Goggles were nice but not nearly as immersive as I had hoped.
Nervous about history of battery issues (swelling).
Mainly because goggles were not all that they are cracked up to be I'm returning the package.
I think I'll wait until at least through summer and see if a Mavic 3 pops up.
