I've been doing a lot of drone research and obviously the two drones that keep popping up on YouTube are the GoPro Karma and the DJI Mavic Pro.
Lately, there's been a number of videos of people flying the GoPro Karma who just have had (and recorded!) terrible experiences with it. The fact that it doesn't hover is one thing but now there seems to be a growing number of users who have experienced the Karma drone literally just losing connection and falling out of the sky. Here are a few videos.
In a few of these cases, GoPro has been contacted and they've set in motion a replacement device but still, these issues seem basic enough that they shouldn't be happening and yet they are. Doesn't bode well for GoPro's future at all...
And one added bonus: Here is iJustine assuming the Karma drone would hover in place (like it should) but instead it goes straight into her house wall and crashes and breaks. GoPro, you've got a dud on your hands.
