¿Es clónica de alguna que conozcáis? Estoy buscando información sobre ella pero no viene casi nada.

La pregunta es, ¿la devuelvo, o me vale para ser un tio educado?.

La verdad es que por precio no tiene competencia. Estaría bien que además sirviera para abonar el jardín.

Un saludo a todos/as y muchas gracias anticipadas por vuestra respuesta.
