We let the racquets and the players do the talking. Here's what a few of them had to say after coming through the Lab.
If you’re particular about your setup, identical frames matched in weight and balance with grip shapes dialed in, this is your place. They reshaped my Yonex EZone frames to match the Head Speed Pro grip exactly. Never thought I could play Yonex. Now I won’t play anything else.
Called looking for a racquet recommendation for my daughter and Ana delivered. She walked me through weight, fit, and frame options, then introduced me to the Demo Program. Our whole family is picking up tennis now and this is the place we trust.
They took the time to ask about my playing style, tension preferences, and even helped me choose the perfect string setup to match my game. The turnaround was super fast, the quality was flawless, and my racquet has never felt better on the court.
I had an excellent experience here. The staff really know their stuff and took the time to help me find the right racquet setup for my game. They strung my racquet perfectly and even gave some helpful tips on tension and grip size. Highly recommend for ballers of all skill levels.
