Mediocre, definitely not worth the money it costs. Mediocre to bad plastics and the buttons are loose from the moment you open the package. Even with the best connection, the sound quality drops significantly. Especially in Athens, and because there is no 100% clear frequency, interference is guaranteed. Also, the farther the device is from the radio, the more intense the interference becomes, and there are interruptions in the sound. Additionally, the microphone is almost unacceptable because it sounds mediocre even if you have your mouth right next to it. Finally, the charging is slow. For this price, try something else. P.S. This refers to the device with the spiral.

I have 2 of these for a year now. Both are excellent, in different cars. In a '99 VW Polo, where the lighter socket is a bit tight, you need to be careful when removing it so as not to damage everything. Of course, it's the car's fault for that...

Something I didn't expect, but it's there, is that it can charge. With new batteries in a 2002 Atos, it charged half of my old phone (Samsung A70) in 15 minutes! It also has a type C port!

Although occasionally it experiences some glitches while listening to music. That is, it gets affected if you pass by another car. It has worked well for me because it functions perfectly with the iPhone and recognizes it as a car playback device. It also answers calls.

I have bought it 2 times at a price below 10 euros.
It is quite good and does not stick.
Finally, it has a good adhesive tape on the back.

Very good, the difficulty in cities is finding a free frequency to use it. Especially if you travel to another city, you may come across stations. Otherwise, very good. I would like a slightly higher volume (you need to increase the radio volume to hear at the same level as the stations)

The product appears to be very high-quality and not cheap at all. It works perfectly at 108.0. It is flawless during calls and does not cut off the sound of the songs at all

Today I received it and used it. I had changed 2-3 gadgets of this type in previous years and it is by far the best. I consider it very good for its price! If you find a clear frequency from radio stations, the sound will have no interference! I use it exclusively with Bluetooth and it saved me a lot of money!

The product is not bad! I believe it can be a solution for people whose car does not have Bluetooth and are looking for a way to listen to music or talk on their phone through their car speakers! However, I don't know what happens in the countryside, but in Athens, the "snow" and interference make it annoying, and this is an uncontrollable disadvantage in my opinion! I initially set it to the frequency 87.6 and then to 103.5 and 107.8, and I didn't see a significant difference, as the interference remained and it wasn't at a level that you could ignore them! The extreme solution is to completely remove the antenna (it improves the interference to some extent - although it doesn't eliminate them), but again, I don't consider it a serious solution! In conclusion, if you are in Athens and you don't mind constantly hearing a "snow" or somewhat moderate interference behind your music, go for it! I haven't tried it in the countryside, and it may be much better!

For its price, it's just what I need to use it in the car with Bluetooth from my phone. The 103.5 works very well in most cases. And I can charge it quickly with fast charge

The best thing for an FM transmitter. I tried the Akai and another one from BaseUs and ended up with this one. There is no interference between Bluetooth 5.0 and the car antenna whatsoever. Any interference you experience with this will be due to not finding an empty frequency.

It worked exactly 3 times. On the fourth, it was dead. Moreover, because the car has 2 slots for chargers, etc., it was also tested on the second one, but still nothing. All other USB chargers work perfectly. The sound quality was not good, barely tolerable. A bad purchase, not even worth returning to the store via courier for replacement or repair. 11.55€ + 2.40€ shipping = 13.95€ wasted out the window.

Good product. Used for music. Connected immediately to the phone. If you want to use it with a card or flash drive, be careful to format it to FAT32 before putting your music inside because it doesn't recognize NTFS

It was mainly purchased to be able to play mp3 songs from my mobile or USB stick or to listen to online radio and have the sound transmitted through the car speakers, and for this job, it is simply excellent. The connection is flawless, the transmission is immediate, and without interference (as long as you find a frequency that is not being used by a radio station. Personally, I use 108.00 and it works perfectly everywhere.)
The minus one star is because the quality in open conversation during the connection with the mobile is mediocre. If you are not interested in this particular feature, then it is worth purchasing 100%

While the sound quality is very good, my voice is heard with significant interruptions to the interlocutor. It is like a defect.

I received it 2 days ago and I am very satisfied with the product. It does exactly what it says without any interference in the sound. You just need to find a frequency with "snow" and synchronize the device to the exact same frequency. Then you connect your phone to the device via Bluetooth and from there on, whatever you hear from your phone is now played through the car's audio system. Satisfied also in terms of calls

(After using it for several days, everything I mentioned still holds true. Additionally, I would like to recommend the frequency 103.5 for Athens, it's almost perfect.)
I usually don't write product reviews, but this wonderful little thing left me amazed.
It transformed my twenty-year-old car radio into a modern one. Flawless in every aspect. Perfect connection with my Android smartphone for calls and radio stations, as long as you find a relatively clear frequency. That didn't pose a problem for me, even though I live in Athens.
It plays USB smoothly up to 32GB and its charger offers fast charging.
I am more than satisfied with what I got for the €14 I spent. I highly recommend it.

I would prefer it to have a power on/off when not in use. Also, since my car has Bluetooth (only for audio) and I prefer my phone to work through that channel, I haven't found a way for them to work simultaneously if it's plugged into the socket when I enter the car. I have to first connect my car's Bluetooth to my phone and then plug in the Transmitter - in this case, it works well. On the positive side, it is sleek and user-friendly.

I have it on the bus and we play songs from YouTube. When someone calls, it answers normally and then it may not continue playing normally, it stops and you have to press the song again. And I would like someone to tell me what we can connect with the plug it has, since I don't have it with technology.

It does not connect, the radio does not work, and overall the worst purchase I have made recently.

Very good for someone who doesn't have a way to connect their phone to the car radio!
In an empty station, there is zero interference, while when there is no empty station, there is interference especially at high volume. Personally, I take out the car antenna and solve the problem

I don't know if I'm doing something wrong, but it squeaks on 's' and 't'. My speakers are fine, and I wonder if it's the device's fault.

Simply perfect.....I use it in the taxi I work in, and in my car....you just find an empty frequency on the radio....!!!!!

Very good transmitter. Easy and automatic connection with iPhone every time the car starts. If you find a good frequency, there is no interference. The charger is also great.

Hello from me as well.
Well, it arrived on time.
I activated it today and I am very satisfied.
If it causes me any problems along the way, I will let you know.
Anyway, for its price, it is cheap

It has two USB ports but you can't use any of them to play a flash drive, only to charge your phone. Sometimes the Bluetooth doesn't work and when you receive a call and pick it up from the machine, it doesn't respond. The good thing is that it measures the battery and power voltage

It is the worst thing really.. It does not have a USB port and has incredibly many sound interferences.. It is not worth its money at all..

Very good product with capabilities of remote play of songs from your mobile to the radio, and even a car kit for hands-free calling, with automated operation (you set it once and when you open it again, it goes to the last function you had.

As for the issue that the previous reviewer faced, it is solved if you press the increase or decrease in volume and then go back to the song, it works normally!
The only thing it lacks is a screen to display the song title from the list of MP3s you have on the SD card, and to deactivate after a period of inactivity to avoid draining the car battery.

The only malfunction is that the "next" button does exactly the same as the "previous" button... Maybe some firmware update...
