Have had a Scout drone for over a year with no problems. Ordered extra blades with the drone just in case. Have used the Scout on July 4th to video fireworks and for my rural fire department's training and calls for service (fires, control burns (CRP burns and controlled structure burns). Wind gusts have introduced it to tree limbs and structures. So far the blades are still intact with no damage. I consider these blades to be high quality and very sturdy. Haven't had to replace any yet but will probably do so just to be safe. Thank you EXO. Great drones and fast service. PS: the scout fits in a pocket on my bunker gear so it's always handy.
