after ordering a batch of these.... i have to say im very disappointed. the durability is horrible (need 2-3 steamed shuttles to last a single match) and if you lose a feather, it starts spinning like crazy. genji shuttles are good for a few rallies, but they are cheap and bad quality. if you are thinking of getting the cheapest ones (practice shuttles) the flight is horrible (feathers weigh more than cork). also, the shuttles are extremely fast and inconsistent. i would not recommend these; all other brand-name shuttles i have seen are better, except for Wilson.
Which one did you order? I myself have tried the Champion Grade and the Tournament Grade, I did not have any problems with the Champion Grade one, but I agree the durability was lacking for the Tourney Grade.
I order the champion grade and tournament grade Genji also. one tube of each. I'm very disappointed in the quality and durability. I would stick to Victor Tourney Blue $15.5 or RSL tourney #1
