I have been using these badminton shuttles for quite some time now and I must say that I am happy with my purchase. As a club level player, I was looking for something that was affordable yet effective on the court. These shuttles certainly fit the bill. Although they tend to fly further than other brands I have used, I have adjusted my game to compensate for this. As for longevity, these shuttles seem to last just as long as the more expensive brands out there. Everyone at my club is satisfied with them and we will continue to use them. Overall, I would definitely recommend these shuttles to any club level player looking for a cost-effective solution.
