Review: Há muitos anos que utilizo transmissores FM no carro para ouvir música, mas este equipamento superou todas as minhas expetativas! Excelente qualidade de som, com possibilidade de regular graves e agudos o que é pouco habitual, e contrariamente a outros equipamentos que já usei, não tem ruídos de fundo e a separação stereo é ótima! Felizmente temos em Portugal duas frequências que não são utilizadas por estações de rádio (87.5 e 108.0) e por isso, sintonizando numa destas frequências, podemos viajar todo o país sem necessidade de mudar de canal devido a interferências. As chamadas telefónicas são perfeitas e não tenho tido reclamações! Equipamento muito fácil de utilizar e o manual tira as dúvidas que possamos ter. Impossível ter melhor relação qualidade/preço. Recomendo!
