I have got at least 10 hours on my blades so far and they still look and feel like new. After paying $3.35 per 2 blades I think it was a good deal.
Of course there is no guarantee on them but I always check each blade before every flight and there is no guarantee on the DJI blades either. At that price I can afford to change blades even if I see a miniature little mark on one of them and I have many new ones in stock.
