Review on KEVENZ 12-Pack Badminton Shuttlecocks, Goose Feather Birdies for High Speed, Stability, and Durability by Steven Lewis

Bought these birds after reading all the positive reviews. We were so disappointed when we went to play! I don't know if it's goose feathers or something, but when you hit a bird it flies down with a sinking rather than a slight motion and flies over the net. They may be too heavy, but we can't use them and it's not interesting to play badminton without being able to volley. I wanted to return the item and to my surprise I had to pay for the return shipping. I'm sure it will cost about 1/3 the cost. Don't waste money like me.
