Review: Transmitter - Great product. Fast shipping. Buy again.
Review: 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.

### ⭐⭐⭐⭐ Excellent
*by I***B on 8 May 2023*

Before purchasing the Nulaxy, I bought and returned two other offerings from Amazon that proved to be poor quality. However, not so with this one. This device actually exposed the poor quality of the UK analogue FM transmitters, because what it sends to my car radio is actually a massive improvement in clarity. It has such excellent fidelity and stereo separation that music tracks from a flash drive fill the interior of the car. It's also clear and sharp enough for audio-books and language learning. To minimize static noise, the volume on the Nulaxy should be turned up full, and thereafter, the loudness controlled by the radio. In my case, I found signal to noise ratio was best at the 88.3 MHz end of the FM band. Oddly enough, I initially experienced a little static at that frequency, but it eventually faded away after a day or two. As for the telephone hands free facility, I have been told that my voice can be heard clearly. If you have a deeply recessed car socket, as is the case with my British Ford Focus, you will find that the Nulaxy won't reach. However, I overcame this issue by using a hard plastic two-way adapter (https://www.amazon.co.uk/Double-Socket-Cigarette-Lighter-Adapter/dp/B003VP1M5I), which is also now available on Amazon. If I had to make one criticism of this product, it would be that the volume control is pointless because, as I mentioned earlier, to achieve best quality reception with lowest noise it needs to be permanently turned up to maximum. It would therefore be a big improvement to redesign the unit so that the volume control is replaced by a fast-forward and reverse facility for audio playback. Such a design modification would be particularly useful when listening to audio-books and foreign language education files. The best that the current design can do is jump forward and back between files, rather than moving within them. Loudness level could then be included in the settings. *UPDATE*: I'm reducing this from 5 stars to 4 stars because it completely destroys radio reception very near the chosen transmission frequency of the Nulaxy, and causes signal reduction of any stations broadcasting at around 10MHz higher or lower than the chosen frequency on the Nulaxy. Unplugging it would correct this situation, but then by doing that you lose the phone hands-free facility.
