Review: Great device, very useful! - This little device is great! I love it! Crystal clear sound quality! Connected just fine! Phone calls worked great too! I like how I can skip songs with the little knob so I don't have to pick up my phone. I also like that I can just press down on the knob to easily pick up phone calls. 10/10 quality, affordable product!
Review: NOTHING BUT GOOD THINGS TO SAY - This Nulaxy Bluetooth unit actually works really well. I was going to buy Bluetooth speakers to clip onto the visor of my 1997 Land Cruiser, and accidentally ran across these little FM xmitter products. There are many brands and models, but this one had a couple of nice features and seemed to come recommended, so I chose it. I tune it to an FM station that has the least static and no signal at all, and I pre-program that frequency to a pushbutton on my radio. The unit connects via Bluetooth almost instantly when the car is started (and a voice notifies me that it's connected), and then on a call, telephone conversation audio comes out clear and smooth. Turn it to its max volume and it may not shake the fenders off your car but it's not bad at all...and that's on a older truck, too. The only music audio I've tried so far is my "Favorites" playlist from a YouTube app. It plays them very nicely. And I can pause them with the multifunction button (and occasionally fast-forward past the ads in between each "track" by turning the multifunction button briefly clockwise...although it sometimes also skips to the entire next track). Fidelity is about as enjoyable as if a radio station was broadcasting the songs. Initially some features weren't working, until I realized that my dashboard cigar lighter is in a recessed dashboard area that's too narrow and the dashboard's plastic was holding the Bluetooth device's "light" button down. This made a number of features not work properly. So I mounted the Nulaxy device on a small extender "stalk" and it works flawlessly. Navigation audio goes silent during a phone call, but that's an iPhone thing…and it comes back automatically and quite instantly when the call terminates. Probably again per the iPhone's own behavior, navigation audio takes precedence over music audio loudness-wise, but the music audio continues playing softly in the background and then comes back to the foreground each time the navigation app stops talking. So I can listen to music while navigating, and it works fine. My strategy if I want to listen to the radio is to listen to whatever station I want...baseball game on AM or whatever...and if a phone call comes in, I just switch the radio quickly to FM and hit the radio's pre-programmed frequency button, and then I answer the call on the Nulaxy device. If I want to initiate a call, I turn the radio to the FM frequency first and then initiate the call on the phone (by typing or by using Siri commands), then converse via the Bluetooth device. The "dial last number called" quick-double-button-press works too...but only seems to work for the last call that I myself initiated, not the last call that called me and spoke with me. Not a big deal there, and that could be an Apple iPhone thing too, for all I know. I'm not sure if Siri commands work without touching the phone...but of course they still work on the phone itself. About the only small wrinkle, and it's just the nature of different signal source amplitudes and not the fault of this device, is that FM radio volume must sometimes be turned up a bit to compete with road noise...so in those cases I need to remember that I had turned the radio volume up before I switch back to the baseball game...or I may hear "Beanball!" or "Kill the umpire!" come out of the speakers really loud. (But since I'm yelling those things at the top of my lungs whenever I listen to a ball game anyway, it's hardly a big deal...) Overall this great little gizmo has it all over my original idea of putting speakers on the visor above my head -- so many limitations and complexities are simplified and improved with this approach compared to separate speakers (which would need to be manually turned on, and frequently recharged, and I'd still have to turn off or pause other audio to make them worthwhile at all). This device is a dirt cheap way of adding full-featured completely satisfying Bluetooth connectivity to my nearly-30-year-old Land Cruiser for a whopping $12.47 Black Friday sale price. Would I buy another? C'mon, man, who the heck needs two older Land Cruisers? : )

### ⭐⭐⭐⭐⭐ Works better than expected.
*by K***T on February 19, 2026*

Very happily surprised with this after trying the bluetooth feature! I wanted to take a chance on this simply because it is cheap and some folks seem happy. So fired up a what I thought dead FM channel and used a fast 2.0 USB. I did not try a 3.0 USB so I cannot say that I gave it that much of a chance but there was some noticeable distortion. This was pretty annoying but I tried out the bluetooth option with my phone and it works 98% clear. I would say better than basic radio but not better than stuff you'd have headphones on for...which is already awesome! No noticeable noise level. Easy to setup, just plug it in. The design is a bit goofy for anyone that has a slanted carlighter. The usb drive slot blocks the change track button but this is no issue with just a charging cord. In terms of charging it was decently fast! I did not try out the other small slots but it has more stuff too. Color changing is I guess nice and the bass booster might be nice but I think it distorts the music a bit too much. At under $10 this was quite an awesome grab.
