Great props and i can confirm this pack contains one 1CW and 1CCW also labeled on the packet as Gemfans. Managed to get these to fit on my F450 with DJI style fitting on the motor. Just used a M6 Star Washer to keep it from moving about. Ring adapters are also included but i did not use them worked fine for me.This prop are unusable, al 4 prop are umbalanced and it is not possible to balance ... i have used a dubro professional balanced but it is ever unbalanced... i am not satisfied...never buy this prop....my dji style 450 fly very well with a plastic propeller 9x45 green... after that i mounted this propelle apc style 1045 it is very unstable and unflyable!!!Very smooth props with a good balancing out of the box, i use them with my Quanum XJ470. 20 minutes flighttime with a 6000mAh battery and 2213 motors are possible.Nice props good quality and they came balanced :DWow, very odd prop with extreme tip oscillation. This prop is only for slow fly and unsuitable for multi-rotors. After balancing the tip oscillation almost destroyed the aircraft.While this is clearly 2 props, it certainly DOESN'T make clear one prop is a puller(tractor) and the 2nd is a pusher. They are NOT 2 of the same type. If you look at the picture is is NOW clear what is being purchased but IS NOT clear in the description.This can definitely take a beating, they are rigid but not so rigid as the Thin Style ones
overall quality looks good, the best I have seen to be honest, now on I will use only Gemfan.Good props but need to be balanced a bit, About the price, nothing to say :)
