Better than expected. Great durability with good performance.
Top of the line pressureless tennis balls. They seem lighter than in years past. Great for training and ball machines.
We've played tennis with these Tretorn tennis balls for over a year now and the nap is pretty thin, but they still have better bounce than the standard tennis balls fresh out of their package. A partner was pretty upset when he realized that his new tennis balls didn't have the play of my year old ones.
