Diadem Premier Extra Duty (72 Ball Case)

Superb Ball

The ball are definitely premium and well deserving of their superb reputation. They have a nice feel and a consistent bounce. I usually play between 90-120 minutes and the balls did not show much degradation during that time period. When I open other cans of balls there is a nice hiss when the can is depressurized. I was surprised when the sound emitted by the Diadem can when opened was more like an explosion than a hiss. The sound startled me and my hitting partner. Lastly, I am not sure what happened to the case or box housing the 24 cans because it arrived in terrible condition. The box was ripped, torn and tattered badly and a lot of tape was used to make sure the box held together. Not a good look and not sure what happened there. But at least the case contained all 24 cans and the cans appear to be fine.

These are high quality balls at a fair price. I have used the cheap Penn's, the cheap Dunlop's, the ATP Dunlop's, Penn Marathon's and Penn Tour balls. The Diadem balls are not too bouncy like the cheap Penn's and do not die quickly, like Wilsons, they are neutral and durable. I will continue to use them.

I bought a couple cases and passed them out to all my tennis group friends, so we have good balls for a month. :) I am Mr. Balls. They are decent quality and seem comparable to major brands, try them and see.
