Funciona bastante bien, pese a que no acaba de apurar en muchos sites, estéticamente está bastante mejor que las de la competencia y tiene margen de mejora. Funciona bien.

A great extension to start accessibility testing - unfortunately important features require a paid Pro account. The reporting and sharing options could be improved.
