I'm sure there are people on here that will disagree with me on this but I have had the stock props snap like that also. After running low on the OEM props I ordered Anbee Propeller Props Blades from Amazon. I found these props to be 0.5 grams heavier and not as silent as the OEM props. Some needed to have the hub sanded down a bit so they spun freely. I have hundreds of flights on these props now as I bought them back in July 30, 2018.
I feel that they are made a little stronger because of the added weight and may last longer then OEM props. I can put up with a little more noise if it means my Anafi keeps flying.
