DJI. They only care about money, they spy on your drones flight info/photos, and they don't care about there customers (In my experience). They have great products, top shelf but with no DJI insurance/Warranty they leave you SOL. And if your unlucky enough to buy any of there products and its flagged as "stolen" or "Locked" they will NOT help you, even if you have a receipt. Also doesn't help that there prices are too much.
Personally I HATE them and I just want to sell my current gear and buy Walksnail.
