Quick and easy to setup

April 10, 2018

Quick and easy to setup. Process: connected to phone via Bluetooth, set channel on FM Transmitter to 87.9 (my preferred station for transmission), changed car stereo to 87.9 FM, started music on phone and auditory perfection ensued. The sound quality is top notch for short radius fm transmission. The next and previous buttons worked seamlessly with my audio apps. The adjustable volume nob makes it easy to adjust the volume, and allows for adjusting on the phone, on the transmitter, and on the stereo as 3 separate adjustments to get the volume exactly where you want it. The long adjustable neck is perfect for keeping it accessible even when cup holders are extended forcing odd angles. Fast charge works great on my Samsung Galaxy S6 phone, as well as simultaneous dual charge. The Microphone on the transmitter works surprisingly well. Call recipients can hear me just fine and I can hear them well. The audio jack works as expected and provides a great way to connect for devices that don't have Bluetooth connectivity. The micro sd slot works great on my 32 gb sd card. Overall I am impressed with this transmitter, and would highly recommend it for both quality and price.

Music plays very softly

March 14, 2018

I have to say I'm disappointed with the unit I got. It looks good, the screen is nice, and it fits well in my car. The problem I have with this is that I wanted this as a Bluetooth bridge between my phone and my car in order to play music, and it doesn't do it very well. I have to turn the volume on the unit all the way up, the volume on my phone all the way up, and the volume on my car stereo all the way up, and it's still barely loud enough to hear over the road noise. I tried connecting my phone through Bluetooth and the aux cable, and it's the same with both. The radio is set on a channel without any stations near it, and I'm not getting static, just not much sound. The unit's status messages are loud and clear, which almost blew me out of the car since the stereo was turned up all the way, so I'm not sure why the music is so quiet.

Good quality, sound, and reasonably priced, but output jack got deffective

April 5, 2019

Color: BlackVerified Purchase

I received the product a few days ago. Set it up and installed into my car's 12V power outlet. It turned on, I tuned it to an unoccupied FM radio station, and I Bluetooth paired it with my cellphone. The pairing went foolproof. A voice message notified me device paired successfully.
I went on and played songs from Youtube. Sound was good, reception was clear, quality of the audio depending on the quality of the source. All is good, I am happy with the product, but it has a culprit. I did not succeed to set it to play an external audio source, via it's 3.5 mm coaxial port, with the supplied cable. Cable is fine, because I used it to connect my ipod directly to the car radio's aux socket. Source plays fine. However thru this device aux port, there is no sound. when inserted, the sound switches from the Bluetooth to silence...
I contacted amazon technical support. They tried to debug it. After doing their research they deemed the device faulty, and they are sending me new replacement item. But here is the issue... when I play the Bluetooth music thru the device, and I hook the cable from the aux port to the radio aux port, it plays loudly and clear !! So the device may not be defective at all... but here is the question... this is a two way input/output port. It should auto detect the audio source and play it thru the radio FM. But it works as an output, but not as an input. I will get the new item and see if the problem is fixed... if it is the same, then there is a trick that it is not noted in the manual, and I do not know what it is.
Otherwise device is fine.
Edit: I contacted the vendor, Leextek which were kind and very prompt. But they say the "aux" port only works as an input when it receive digital music in formats like mp3, wav, etc. This sounds to me absurd, because I don't know of any audio device that outputs a digital signal, except for fiber optic outlets. But virtually all music player output an analogue signal, thru their audio outlet. So this accepts digital input only, while as output it delivers analogue audio?
This seems absurd...

Edit: Got my replacement unit, that worked like the 1st one. No input via the aux outlet. Product worked well via the aux outlet and via FM. Less that 2 months in service and the output jack started to malfunction. I removed the unit and disassembled it. The output jack un-soldered/broke, and was contacting only one point. Upon examining it, it broke completely. There was no way to solder it, because two out of 4 contacts came off with the flexible cirvuit board, it was soldered to. I reassembled the unit (without the jack) and now it works via the FM radio and Bluetooth only.
The unit was static and was not exposed to vibrations of any kind. I regret to say this is poor, cheap manufacturing and I won't buy this unit again.

Edit: So to make things clear.. the 2nd unit they sent as repplacement, works well on bluetotth and also output good and clear signal from the coaxial jack. I could not use it to accept a sourse input. After a certain port, the coaxial port broke and was unusable. Uppn opening the device, I found out it had 4 contacts, but only two were soldered, and it broke. I continued to use it as a bluetooth only, until I visited walmart and incidentally I found there a similar product. For $29 something. But this also had a USB port for USB sources. I brought it home, installed it and works like a charm. Not to mention that the coaxial port works as output, and also accepts audio input. I am very pleased with the new bluetootk device. The model is ROAV F3. Works as advertised and very well. The Summind product is propably defective at the production line (they forgot to solder 2 pins on the coaxial jacket) For your information.
I reduced the number of stars to only 2. Product is still usable, as bluetooth.

Would NOT Purchase Again

May 31, 2019

Color: BlueVerified Purchase

Everything works fine except the main things to me. 1. Just because its on that spiral looking piece doesnt mean you can adjust it 2. The sound is VERY low. I will be posting pix to give you a better understanding. With the volume all the way up on my phone and the bluetooth I still have to turn my radio volume all the way up just to get a lil base..and I have BIG bass. The fast charging is great..so far. But we all know its not the day of that we worry about, its the 1 month later BUT I wont have this product long enough. My family dollar tape plays better. Will be returning

Need 20/20 to read display. DISPLAY IS TINY

April 14, 2018

Color: BlackVerified Purchase

I just received this today and was really surprised at how easy to setup and the ease of connecting to my phones. The UPSIDE to my review is I love the rapid charge, can play Pandora instead of listening to the crap on the radio and I now have hands free. My phone announces calls so I do not have to strain my eyes to see the TINY display area. The DOWNSIDE to this product is the actual size. Is half the size of my palm and the display if super tiny. I cannot read display unless I pull over and put my reading glasses on to see the display.
This is my first day with it like I said. Not really sure if I will change my review later mainly because of the tiny display.

returning this unit

January 23, 2019

Color: BlackVerified Purchase

I bought this unit hoping it would make me want to keep my car. I need Bluetooth for hands-free calling and I wanted to be able to stream Apple music from my phone over Bluetooth. I do not have an auxiliary plug, so Bluetooth is my only option. The hands-free calling is pretty good, sound was clear coming in, my husband said out-going sound was a bit soft though. When I tried to play music I could barely hear it, even with my car volume, and the volume on the unit turned all the way up. Not what I was hoping for. I'm going to try a different one.

Sound volume stinks

January 5, 2018

Color: BlackVerified Purchase

Works alright. I've only had it 1 day so I'll update if anything changes. Volume is weak, I have to turn device and stereo up all the way to hear it. I think based off the sound I wouldn't buy it again. I thought it would be good based off the reviews and that's why I'm adding mine.

January 16, 2018

Color: BlackVerified Purchase

Item makes a constant buzzing sound no matter what station I used. Also, if your cigarette lighter slot is under the dashboard like mine, you can barely get it in the slot and then the console sits low and almost inside the compartment where I keep things (which makes them almost inaccessible too). I only bought it because my in car Bluetooth stopped working (I'm told it's an Apple issue), not what I expected.

After 9 months this no longer works

December 17, 2018

Color: BlackVerified Purchase

I've had this transmitter for about 9 months and this morning it gave out on me. So as I was pulling my transmitter out of the the cigarette lighter outlet all of the parts that hook into it flew out so now I'm not able to use this anymore. The other thing I didn't like about this transmitter is that when you turn off your car it stays on so it's slowly draining your car battery. When it did work it had great sound and was easy to use but due to how quickly it broke I will not be purchasing this again.

Bluetooth works, aux does not.

October 15, 2019

Color: BlueVerified Purchase

If you're looking for a device to connect to your phone via Bluetooth, this works great. The controls are tactile. If you were hoping to use the aux to connect to an MP3 player like an iPod Classic, you're better off trying something else. I've tried everything but I can't get my device to play. Kind of disappointed I wanted this to work with both my phone and my iPod.

Cheap quality

August 12, 2019

Color: BlackVerified Purchase

I had this thing for 4 months.. my first issue was it is not loud at all so my music kinda sucks coming through the speakers. But I've had ot for 4 months and discovered that the adapter part you put into your lighter plug in the car was completely broken off and is literally STUCK in my lighter plug. So now I have a broken bluetooth and its stuck inside my car. I rarely ever touch it. Its %99.9 of the time inside the port and I basically never take it out so it was not roughed up or treated poorly. I'm pretty upset about it though.
