Why we don’t review rackets

Most padel sites assign subjective 9/10 review scores to whichever brand sends free test palas or pays the highest affiliate bounty. We don’t accept free gear and we don’t pretend to test rackets on court. Instead, we publish official manufacturer engineering data, run reproducible math on balance and core density, and let you compare rackets honestly.
