None of the USB drives I tried work, even though they had the correct format (FAT32). So, I guess I got a defective one.
P.S.: I replaced it, but nothing changed. I’ve tried 7 USB drives and it doesn’t recognize any of them.

It gets a little static when you pass through a mountainous area or an area without good reception, but it does its job as it should.

I have bought 2 for myself, for cars, and for acquaintances and friends. I have had them for over 2 years. Amazing sound. I recommend it.

Perfect acoustics, especially if both the car radio and the transmitter are tuned to the frequency of 108.

Okay, very good as long as you can find an empty frequency (and without interference) on FM. In Thessaloniki, this is very difficult!

Excellent in everything. Be careful what you say because anyone who has tuned the radio to the same frequency can hear you.

perfect!!!!

It produces good sound and connects easily. It just needs the engine to be running in order to provide power for it to operate.

It connects in 3-5 seconds, has perfect sound without interference in music from the mobile, while another one I had was exactly the opposite. During phone calls, they hear me perfectly without my interlocutor realizing whether it is directly from the mobile or from the transmitter. In my car, it also found the right spot with its base.

The car volume needs to be increased a lot in order to hear the transmission from the transmitter, which means that if I switch to a radio station, I have to remember to lower the volume. Other than that, easy and quick connectivity with the phone, I haven't faced any problems with sudden disconnections or strong interference.

I am very satisfied with the product. It delivers very good quality for both music and calls. And it has a good microphone, which can be placed high up with a cable so you can be heard well, not like most of these devices that are down by the lighter and are quite far away for you to be heard when you speak. For me, the 3.5mm jack was also convenient since I found a cable and connected directly from there to the car stereo, so everything sounds perfect and I don't need the radio at all. So in the end, I use it as a Bluetooth transmitter directly to the stereo.
The first one I received was defective (the caller's voice wasn't clear while the music was perfect), but I returned it quickly and effortlessly through Skroutz and SkroutzPoint, and in 3-4 days I had a new one that works perfectly.

As long as you find the right station, it's very clear. In Thessaloniki I use 92.7, but if that doesn't work for you, keep searching

It was very convenient for me: at 108Mhz it works very well, without interference, it has a long cable and can be placed in a different spot from the power supply, it does quick charging, shows the battery voltage as soon as you start the engine, and has a good price.

Excellent value for its price. Very good response to sound on the phone. The only negative is that it does not accept USB flash drives

As a radio it is excellent, and the buttons help. Regarding calls, I can't say that the microphone it has is satisfactory.

It is very good for its price. On some frequencies it causes interference, but if you find the right one (e.g. for me in Heraklion, Crete it is 87.5... I don't know about other places) then it works perfectly and the sound is clear. I highly recommend it to anyone who wants Bluetooth in their car without getting a new radio system!

Its connection is simply super easy and since I installed it in the car I have stopped listening to the radio! Besides that, when someone calls you, the communication is clear.. I have it mounted on the air vents and I am heard very clearly while driving, but when the air-condition is on or air comes out of the vents, you are not heard clearly so you either have to turn it off or bring it closer to your mouth

for its price it's ok, but it's not amazing. for old vehicles that don't have Bluetooth and a USB port, it does the job.

Poor build quality, from the moment it came out of the packaging one of the two parts broke and a month later it was completely destroyed.

Very good for its price. The microphone is quite powerful and in a 2008 Citroen C4 it worked immediately with the central audio system

For €20, it is a very decent transmitter, I have had it for over a year and I am satisfied, quick connection to Bluetooth and almost zero interference and noise in the sound, I highly recommend it for anyone looking for a cheap and reliable transmitter

Reading the reviews, I think it helped me choose it, very easy to adjust, pay attention to the incoming sound when they call you, it sounds low. To fix it, while they are talking to you, raise the volume from your phone and it will be just fine

It is a perfect choice for a Bluetooth transmitter! I have bought 4 for friends and they are all satisfied. Easy connection, it has 2 USB ports for charging, as it plugs into the lighter and under other conditions it would be a problem, good microphone for calls and it also has lights that you can change the color and even turn it off completely!

I have been using it for 1 year now. Easy to set up, you set it up once easily and it never loses connection. There are no disconnections. The 2 USB ports it provides work perfectly. Its microphone is not the best but for its price it is excellent. It connects with Androids and iPhones perfectly, quickly and without disconnections.

The 4 stars are due to its unbeatable price and because it generally does what it promises. It is an ideal purchase for someone with an old car that cannot upgrade its sound system to Android/Car Play, etc. For an old car, it can solve the issue of connecting the phone to the speakers. You hear the caller perfectly - unfortunately, at a very low volume. This means that as soon as you answer a call, you have to turn the sound system to a very high volume and then be careful to turn it down immediately when it returns to the main audio source like the radio or CD. Where it is COMPLETELY disappointing is in the quality of its microphone, meaning how others hear you when you speak through it. A bucket, a well, and all that. The problem is mitigated if you place it very close to your mouth or, for example, on the driver's sun visor, but in this case, you have to manage (if you find a way) the cables.

I have had it for about 1 year. I got it as a gift for my friends too! It is worth the money. It does exactly what it promises! The installation is super easy! On calls, it works great; I can hear and be heard without any issues. I recommend it!

Very convenient, of course the classic problem is hoping that no one around has your frequency

Today I tried it, it works perfectly with normal sound reproduction. The installation is very easy, you plug it into the car's port, set the radio to 87.5, and connect via Bluetooth from your phone.

Absolutely satisfied with the product. Clear upgrade from the previous one I had. Fewer interferences, without "disturbing" the signal from area to area. I always have it on Bluetooth for music. For calls, it's good; I can hear and be heard just fine. I have no opinion on the USB ports, as they haven't been used.
