72 NEW TRETORN X MICRO CELL TENNIS BALLS. Tretorn micro cell balls are equally suited for the frequent competition player as the occational recreational player. Simply he best choice for the majority of players.
Excellent pressureless ball with a bit high price tag
I had a short normal tennis hit with these balls and they do not feel bad at all but I purchased them mainly for my ballmachine. These pressureless balls are way better then the ones I used before. Only had one ballmachine session with them but I like them a lot. They are not as hard as most of the other pressureless balls and felt easier on the elbow. They behaved a bit like the Artengo TB930 tennis balls which I use a lot lately. They are a bit on the firmer side.
You can see them on the photo in my Kollectaball K-Hopper pickup cage. This is how I store them after picking the balls up at the end of a training session, removed from the K-Hopper frame. I bought an extra cage so one has normal balls in it and the other that you see on the photo has the Tretorn Micro X cell balls in it so easy to change from one to the other.
The only problem I had is the higher price tag then what I wanted to pay for these.
Time will tell how long they are going to last so I cannot report on that.
