DURASMASH Excellent Grade Premium Goose Feather Badminton Shuttlecock Multi-Pack (Master DS-50 [5Pack])

I am a relatively high level badminton player, but haven't played tournaments in a while. Recently started playing again, bought these for the playing sessions. Despite the claims that these are high quality and long lasting, they do not last at all. The feathers break relatively easily and barely last one game before becoming unplayable. Compared with the high quality Yonex shuttlecocks that other players used, these really don't compare. So although the Yonex cost twice as much, I'll be buying them instead.
