All I can say is that it barely lasted 2 weeks before the strings snapped, the edges tore and the grip came off. The shuttle cocks barely lasted a couple of days each.
This is very cheap and the quality proves its worth – its like a disposable item that you can buy and then throw away after a few days.
Its much better getting a cheap yonex with some shuttles even if it means spending a bit more.
My overall rating : 1/10
