I completely agree! And yes, you're correct. The "DJI Store" link on the Mavic 4 product page is a ruse to make buyers think they are purchasing from DJI. Shame on Amazon for not policing this kind of activity.
Yeah, done lots of lawn mowing as well as I keep on forgetting my landing pad! I'm thinking they are holding up better than my Air2S although I haven't been as stupid with the new drone.
I’ve had good luck with my props too. Just had it out where my Air3S slipped off while landing on the edge of the landing pad placed top of 3-4 inches of grass. It angled/sloped into the grass before shutting off. I think it did some lawn mowing...
