My bad, they're all 9450, and yes these are legit, I didn't know normal props came with stripes, I thought just the CF ones do.

That's what I thought also. My original props had color coded hubs and were solid white bI have since upgraded to the carbon fiber reinforced black and yellow and I'm very happy with them so far
I fly with carbon props with metal inserts. No problem what so ever. I adjusted the braking to minimal just to ease my mind. Never used the original props so can't compare. While flying planes I used wooden props because of the stifness. Nylon props just deform under load and their pitch change while revving up.
Check the hub.
If they are metal then best advice is 'Don't use them'.
Metal might mess up the threads on the motors and will/might come off, if anything happens i.e manufacturers defect then you know what DJI are going to say if your under warranty.
I don't believe mine is under warranty anymore. (Some of the parts anyways) I'll never know how they work if I don't try them. I had no issues on my p1. I'll try them out on the P3.
Everyone on here says don't use carbon fiber. I'm going to buy a set and test them. I had a set on my p1 and loved them. Unless someone can provide creditable information that they are not good for my phantom.
I have a set of original carbon fiber set from DJI.
They are ok and see no justification for having to pay extra money for them as they seem to perform the same as the normal white props, if there is any performance then it is totally not noticeable, the only advice on them is not worth the extra money apart from looking good and are a stiffer then the white ones.
Everyone has their own choice/opinion, just my thought is you can have 2 pairs of normal props with the same price for 1 pair of carbon fiber prop price.
Have you compared them in healthydrones? I see a difference when I put on new balanced props. I'll never know unless I try. I see a lot of people commenting about props that have not tried them. It all just hearsay.
