GoPro Karma Built-in Nut Upgrade Propellers - MR KR 10x4.5 Set x4 Black

The propellers work excellent with my GoPro karma drone ok.

Good Service Good delivery time

Easy to order and quick shipment. I borrowed my sons drone flipped it over and broke all of the props. I ordered some of these and received them in a couple of days. Since then I have flown it onto the side of a retaining wall and into a tree. The props are roughed up a bit from abrasion on the retaining wall but they are still flying. A much better product than the factory props. Oh and they make a lot less noise. A great choice!
