Great while it lasted.

It worked really well. I really like this more than others I've had. It was easy to pair, had enough functionality for me. Could connect multiple ways. But it wasn't durable enough for me. If you're like me and your cigarette lighter does not turn off with the car you may feel the need to remove it when exiting the car. Well first the screw cap holding the spring and fuse unscrewed which was fine until it unscrewed inside the cigarette lighter causing me to blow a fuse fetching it out. Then the screw where it adjust its angle became stripped and would not hold its angle. Then it broke at the joint. I still used it until the wires broke and it no longer functioned.

Works great

We had one of these a long time ago so when I needed a new one I looked for a similar product. This one came up in the updated version. I’ve had it at least a year and use it every time I drive somewhere. It works great and is very easy to use. The sound quality is good but when u have it at the max volume it tends to get distorted. You can fix this by turning down your phone’s volume till it’s clear again. Of course it’s not as loud as you wanted it but it’s a compromise you have to make with this thing. Also I have a little trouble charging my phone when it’s hooked up to this device but Idk if it’s the device or my phone. Those are the only problems I’ve had with it. It is very easy to use and you should be able to find. Good reliable station number to use consistently. It’s still going strong and hasn’t broke at all since I bought it. I’d still give it 4 stars and would buy again. Recommended

Best FM Transmitter I've Come across

I have had my Nulaxy Bluetooth FM Transmitter for a few months now and couldn't be more pleased with it. I am not at fan of listening to the constant babble on local radio, that's supposed to be playing music nor their practice of playing the same 10 songs over and over again; I much prefer to listen to streaming music or the music I have downloaded on my phone but, not having a tape deck or an auxiliary connection in my 2004 Chevy Cavalier made that difficult. Once I found out about FM transmitters I began my search for one that actually did what it was supposed to, that did it consistently and reliably and that wasn't a hassle to use. Many of the first ones I tried were not Bluetooth so I had to fiddle with an inconvenient cord to connect my phone to those devices but even beyond that, they all were unreliable when it came to staying consistently connected to any given radio station and didn't provide clear, quality sound without static. After searching through many different brands of FM transmitters and reading tons of reviews, I decided to give this Nulaxy Bluetooth FM Transmitter a try, and I am beyond happy that I did! It was extremely easy to connect via Bluetooth to my phone, and once done it always remembers it and automatically connects when I plug it in to my cars lighter port. The very first free radio station I selected to transmit my music through connected quickly and easily and the Nulaxy FM Transmitter remembers the station even when it has been disconnected from the lighter port so that I don't have to reset the station every time I plug it in like I had to do with all the others that I had tried before this one. I have encountered little to no static or interruptions in sound and I never have to fiddle around trying to adjust the radio dial to get a better connection like I always had to do before with other transmitters. It's such a great product, at such a reasonable price that I bought one for my brother for Christmas and he loves it. My daughter has finally gotten her own as well, so she doesn't need to keep borrowing mine lol. I know this is a really long review so if you just skipped to the end lol ... This is a great product and I don't think you'll regret giving it a try!

This little thing is amazing!

After reading many reviews I would like to address several issues here. First I have experienced no static at all, depending on the quality of the digital download on my iPhone - for example my ABBA, Meatloaf, Cheap Trick play perfectly but for some reason the Les Miz movie soundtrack does have some occasional static. I have experienced no problem with the Jack fitting in either of my cigarette lighters ports. My daughter set this up for me in about three minutes and immediately started agitating for me to buy her one!! If it only lasts a month or two I can still buy 20 for what it would cost me to upgrade my stereo. One tip… This manufacturer offers an 18 Months upgrade to the warranty for free so I would not buy the Amazon 24 month warranty in the future.

Plug into AUX input for better sound

Very easy to use, build quality, but the sound quality is just average. I had to use my AUX input from the unit to get better sound. Thru the FM station is. Very BAD. You will have to connect your phone to the unit, then use the little cable provide and plug it into the AUX port. With my car, plugging into the AUX port I have to turn the volume to the Max to get average sound. I may have to adjust my radio settings, but the sound is much plbetter plugged in. The Bluetooth connect is very good and very easy. It's nice to be able to keep my phone in my pocket after the phone connects to the unit. I can change the songs thru the unit and pick up a call. I haven't used the call feature yet to check the quality of having a conversion. All and all I suggest to get one, but plug it into the AUX input.

but decided to give it a shot and am glad I did

I don't normally write reviews,but this little device impressed me enough I felt it worthy. Initially I was suspect because it was a generic foreign brand, but decided to give it a shot and am glad I did. For the cost this little things provides some awesome functionality. Tunes loaded flawlessly off my SD and USB stick the first time I tried them. So far I have driven over 1500 miles while using this thing and 99% of the time the signal sounded perfect with no fuzz or interference. (I use 107.9FM) The few times I did get a little static I was in a heavily urban area like Chicago and it was momentary. Being able to swap USBs on the fly is really cool and lets me have different genres I can quickly switch between. Very happy with my purchase. It turned out to be the perfect solution I was looking for. Of course this device isn't all roses. The interface for selecting your music isn't very good and navigating can be a bit cumbersome. With thousands of songs it can get out of control if you want to find a specific song. This is the only real downside I've found so far, and as long as you know that going in it's not so bad. It forces me to curate what I listen to more close rather then tossing tons of stuff on there to sort through later. I highly recommend this if you are looking for a cheap way to play MP3s on a car stereo that doesnt have AUX or cassette decks. note: I have not tested the Bluetooth functionality at all.

the product came in perfect condition package very well the only reason I returned ...

The transmitter came on time :) I returned it though nothing to do with the product.. the product came in perfect condition package very well the only reason I returned it was because I have my phone on a magnetic knob on the vent so it was interfering with my transfer. I gave it a 5×-star because the product came in perfect condition it was nothing wrong with it and I'm pretty sure if I would had moved the magnet that was holding my phone I'm positive that the transmitter would have work a 100%

Overall great device; works well and is very easy to use

To begin, this FM transmitter does its job well. It was very quick and simple to set up, and the Bluetooth pairing went smoothly (used with iPhone). Altogether it only took about a minute. As for the actual performance of the device, playing music and taking calls went smoothly and sounded pretty good. One of the only drawbacks was the quality of the microphone, but it was still very understandable for the person on the other end. I haven't been able to test playing music from a microSD card yet, but playing music from a flash drive does work. The USB ports work nicely for charging devices as well. My only other complaint would be that the device fits pretty tightly in the plug, making it fairly difficult to get out, although this isn't something I have to do often. Overall, this product is of very good quality, and good value for the price. I would recommend it to anyone looking for an FM transmitter for their car. Pros: - Quick and easy setup - Good sound quality - Volume control on the device - Decent sized screen - Adjustable angle Cons: - Mic quality is less-than-optimal - Fits a little too tightly in the plug

Are you looking for a bluetooth transmitter? - GET THIS ONE!

I had big expectations from this little gadget and it exceeded all my expectations. It was extremely easy to set up, literally selected the channel and that was it. It is extremely quick to pair with my iPhone 7 and stays connected. Volume control comes in very handy, I have it mounted by my gear stick. It's like this company thought about everything when designing this product, it features USB flash drive, memory card option, power out to phones/ tablets/ portable battery banks/ USB light/ USB fan or any 5v gadget.

Excellent device, with Aux output

Excellent transmitter and mp3 player. I tried another brand, but settled on this one because a) I like the display screen, and b) I really wanted the AUX output. My car has an AUX input, so this device connects easily and simply, with better audio than going through FM. The display screen is not great -- the song titles are hard to read -- but it's OK, and it's certainly better than nothing. Plus, at this price point, I wasn't expecting a smartphone-quality display. Also, my device included a card that gave me an 18-month warranty, as long as I registered on the Nulaxy website.
