4 Pairs Replacement 9450 Self-Tightening CW/CCW Propellers for DJI Phantom 2, 3 Professional, Advanced, Standard, and 4K (White)

Work is good or better than original equipment in my opinion

Four Pairs Means Two Sets Of Blades and I knew this before purchase. I would suggest doubling this order to have an extra set since they came through very high quality.

Yes, these are less expensive than DJI 9450 props. No, they are not "exactly" the same as DJI - these are not quite as stiff. Yes, I had to spend time balancing each one of these (most DJI's come closely balanced). Yes, these props have survived some less than optimal landings of my UPAir One Plus 4K Wifi drone (which I really like). I'm using these on the UPAir now with great results. They may be a little noisier then DJI's but not by much. Video shot with these props was a little shakey - but after the props were carefully balanced that was resolved. So, I'm very pleased with these props and would not hesitate to buy more. If they were a little stiffer and came balanced, I'd give them 5 stars.

The media could not be loaded.  My drone fly’s perfect and performs great with

I like how fast they got to me. An I use them for my phantom 3 standard don't really like how easy they break but I guess there is a reason for it.

Fit my DJI 3 standard perfectlyLittle stiffer than the factory and louder but worked as you’d expect.Great value for two sets of props.

After installing my drone was not air worthy, would shake and was very unstable I put on the original propeller that are quite literally missing material on them and it still flys perfect damaged.

I put 2 of these props on after a small (ahem) incident involving a tree. It was all the tree's fault. And without anything to scientifically compare it to I believe that the new props are quieter than the old ones. There is a high pitch whine that is missing. I cant say anything about power because i am going slow to avoid drone eating trees.
