DIRECTOR OF COACHING AND DEVELOPMENT AT SMASH TENNIS
The system definitely calms things down on the court. I didn’t have to solve any line call disputes on the court and the players’ stress levels seemed lower, so there were fewer instances where I had to keep an eye on their conduct. The live stream and live scores allowed me to keep track of the matches from the tournament desk, which made my job a whole lot easier.
David Gustafsson
CLUB MANAGER AT FAIRPLAY TK
We are very excited about the Zenniz technology that is available for use in our facility; Zenniz as a product is a ‘perfect match’ for our needs. It is simple and fun to use, suitable for both competitive players and recreational players.

MEN'S TENNIS HEAD COACH AT YALE UNIVERSITY
We're super impressed with the system, especially with the ease of use in the match play. When it comes to line calling and overall match experience, it’s the best we've seen. We had a couple of disputes about some calls and the device resolved them quickly.

HEAD OF TENNIS AT KB TENNIS
Our experience with Zenniz has been extremely positive. Players have been keen to try the system as it is easy to use. The coaches love it and use it almost every time. For us, it's a new thing to go the IT way and look at tennis in a different way.
