Props looks nice and seem very durable. I have had some chrashes with my drone already and yet I have not needed to replace them. But be aware that the prop is 7.5mm thick. With the length of my motorthread I could barely tighten the nuts. I do not understand why they do not make the prop a little slimmer. For example 6mm thick. This is still enough for the blades of the props to connect to the center, but makes it better to attach those to the motorthreads. It is even less material for the manufacturer.
good product, very fast delivery
