Are Ruko drones a real alternative to DJI?

Ruko drones come in well under DJI's price for comparable battery life and weight, and verified-purchase reviewers at Best Buy report clear footage and stable gimbal performance. However, an expert review in our data (space.com) explicitly says image quality lets the F11PRO 2 down despite its '6K' marketing, and the U11MINI's review base is still small. They're credible budget picks, not DJI replacements.
