Gemfan D90S 3-Blade Proppeller for 3.5 inch Cinewhoop Props 3 holes 1.5mm for RC FPV Quadcopter Drone 16 Pcs 8CW 8CCW

Slapped these on my cinelog 35 V2 and haven't been disappointed

Excited to recieve my props I immediately put a set on my new cinewhoop build. Took it out to fly on its maiden flight. Set the drone down on the ground...a little bouncy. BAM! prop completely shattered pieces everywhere. Ok, so put on another one....again..shattered into pieces. I am now on my 4 prop within 3 days of recieving them. I am normally impressed with this brand of props and their durability. Perhaps I got the sets that were made on friday?? These things shatter like polycarbonate not the normal material I am used to with this brand. I have this same brand on my 8 inch quad and they are very durable, but not these on a 2.5 inch ducted quad. Id love to provide a picture of them but they shattered and scattered all over the field. Based on my experience I cannot recommend these at all.

Out of the box, the inserts that go into the center of the props do not fit. I can't tell if it's because the whole in center of blades or the inserts themselves. I managed to insert 2 after some fine sanding of insert and filing of center hole of propeller. I only gave 2 stars because once I was able to install the set I did they flew fine.
