We experimentally test the universality of the Anderson three dimensional metal-insulator transition. Nine sets of parameters controlling the microscopic details of this second order phase transition have been tested. The corresponding critical exponents are independent (within $2\sigma$) of these microscopic details, and the average value $1.63\pm0.05$ is in very good agreement with the numerically predicted value, $\nu = 1.58$.
