To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This shuttlecock back is pathetic. It's not at all durable and rarely sustain 2-3 games. Instead of this, go for Yonex Mavis 10 Blue Cap which sustains far more than this and even performs better. I just went for this because it looks and costs same as Yonex Mavis 10 and I got it cheaper on Amazon Lightning deal, but at the end I found it costlier as this pack couldn't even sustain 3 months at my usage while Yonex one sustains more than thrice with better performance.
