PENIVO Tello propller Pack of 5 Set, Quick Release Propellers Replacement CCW CW Props Propellers for Tello Drone Accessories

I was a little skeptical at first since they are the original propellers, they are little thinner in kind than the ones that came with the drone, but they are holding up great thus far

not strong enough. they fit fine, but they are to weak. I lost 4 propellers in one crash. ;-(
