Butterfly Easy Ball 40+

I didn't like the bty ball. The ball looks very weird, almost transparent.
The ball is durable and cheap but I found the bounce completely different than the other balls in the league i.e. tibhar, xushoafa.
The sound is also curious, different than the other plastic ball.

I've tried 4 plastic balls (tibhar, xushoafa, joola and bty) and I found this the worst.
