Excelente transmissor
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!

For £20 odd quid it's bloody marvellous - MP3 music problems solved in my old Shogun.
Oh my goodness - this little thing is great. My expectations for 20 odd quid were not high, but I needed something to play my MP3 collection through my car stereo (i have an older car with a tape player, a CD changer but no AUX input or Bluetooth. This worked out of the box with my 64 GB ExFAT USB stick (and I am able to browser folders / albums through its mini file browser) . Sound quality is fine - you'll want to tweak the Treble & Bass. I tuned it to an empty frequency at the lower end of the FM band (seems perfectly fine) - I can always easily retune it if I drive in London for example and get swamped by local stations etc. I have tested its mobile hands free Bluetooth mode - no problems - not top notch fidelity on voice, but absolutely fine. Value: five 5 stars Features: 5 stars Ease of use: 5 stars For £20'ish quid! It's bloody marvellous - music problems solved in my old Shogun.

NULAXY Bluetooth transmitter
I recently gifted my husband the NULAXY Bluetooth FM Transmitter, and it has been a fantastic addition to his car! The setup was incredibly easy; he just plugged it into the car's cigarette lighter, and it connected effortlessly to his smartphone via Bluetooth. One of the standout features is the crystal-clear sound quality. Whether he’s listening to his favorite music or taking calls, the audio comes through without any distortion. The built-in microphone picks up his voice clearly, making hands-free calling a breeze. The LCD display is a nice touch, showing the frequency and battery status, and the USB ports provide convenient charging options for his devices. He loves being able to stream his playlists and podcasts directly through the car's stereo system. Overall, the NULAXY Bluetooth FM Transmitter has made his driving experience more enjoyable and connected. It’s user-friendly, reliable, and an excellent value for the price. Highly recommended for anyone looking to upgrade their car audio setup!

Top Super
Absolut genial, im 12V Buchse eingesteckt auf dem radio die Frequenz eingestellt und los giengs. USB Stik mit Musik funktioniert, bluetooth verbindet sich und man kann auch über Kabel an die AUX beim Radio sich verbinden, einfach gesagt tolles Ding, jeder Zeit empfehlenswert. Danke

Bon appareil
Le rendu est bon, l'installation facile et le prix très correct. Juste, pour moi, un très léger bémol, il n'y a pas de commande marche-arrêt. On le branche et il fonctionne. N'en ayant pas forcément besoin tout le temps, je suis obligé de le retirer et le remettre selon le cas. Est-ce qu'à force cela ne dégradera pas la prise allume cigare ? Je ne sais pas. Peut être oui peut être non
