Honestly so far so good got love the multi color set of props available it has a pretty good set of pros some including that you can fit these on a dji neo 1 and 2 .
But one major Con is you need separate M1.2 X 6mm screws which in terms you may need to loctite unless you can find 1.2 X 7mm hex head screws and the 2nd con is more blades does equal less droning noise but it means your motors work harder and drain your flight time by 2 or 3 minutes (this for a neo 2 prescriptive) probably less then 10 or 20 seconds less on a proper FPV drone but other then that worth buying bought the color palette heck I even bought the D51 2020/ 4 which the same prop but as a 4 blade instead but saldy there sold out and dont come in multi colors

But definitely worth buying spares for

Gemfan D51 (2020-5) Ducted Durable 5 Blade Prop

Dont work great on shallow duct frames. But on my 2 whoops with deeper ducts, these work flawless.

Good props
