I don’t know if anyone here has purchased anything from MasterAirscrew before or not, but if you haven’t then beware. Do not order the Endure folding props for the Phantom 4 Pro. They are not well balanced and actually shook the drone so much that it almost popped the battery out. I attempted to contact them twice and never got a response.
I’m not going to retract my statement, but I need to give MAS a nod. After hammering them on their contact form I promptly received a Return label, a refund and an apology. I may try a pair of their solid props but the foldables are still a no-go.
