Worst balls in history
 

Officially Slazenger Hydroguard (4 ball cans). A partner bought a case of these and at least 1 ball breaks without fail. 4 (3hr) sessions, a fresh can each time. Yesterday was a record. 3/4 balls broke. Unbelievable!

I popped 2/3 Dunlop Hardcourt balls(the heavy and hard cheap ones in the green can) in an hour with a friend on a hot day. Are you sure its not a bad can?

More like the whole case. We have a full case of these balls and had at least 1 ball break in each can so far.

Did you try the balls before buying the case? If you got a defective case then you might get a refund.

Yeah I knew beforehand these were bad balls overall. One of the guys in the group bought the case without inquiring first. He's trying to exchange them for a different model same brand.

The felt gets really worn out after about an hour and looks really bad after a whole session. I'm not sure what the concept of having water proof balls are. Nobody purposely plays in the rain do they?

Yeah the only reason anyone would want water proof balls would be in very humid conditions, by the pool, or after it rains. I'll make sure to stay away from this ball.

Donation to a dog park sounds like a good alternative...maybe they're spittle-resistant!

My all-time ball fail were the Tretorn pressureless variety when playing indoors on cold, early mornings in a bubble-enclosed club in NYC...no bounce whatsoever so we had to buy a can at the proshop.
