    I've been using them for more than 10 years and I adore your system also because my size isn't there, having small feet. Last year there, with a new boot, they put me another brand but it didn't heat well and I asked them to replace yours

    La relación calidad precio es buena si las comparas con otras baterías que duran menos.
