Excellent value for money!!

Unfortunately, the speaker broke. Maybe I got a defective one

Excellent little radio, I found it for 12 euros from China, strong and good sound pleasantly surprises, convenient to take it outside, fits easily in the pocket, amazing choice for its price

Overpriced... it doesn't have user instructions in Greek... otherwise excellent!
Very good sound, recording, very good signal. You don't even need to open the antenna.

Very good. The biggest advantage in my opinion is that you can insert an SD card and write songs and listen to them.

There are 2 different versions of the firmware, the newer one can read songs randomly as well as sequentially, while the older one can only read them sequentially.

Another advantage is that it has a built-in battery and you can simply charge it with a USB. As for radio reception, it is relatively good, but the handling is not very convenient for searching stations. The best thing is to save some stations and that's it.

The price in China is around 12-15 euros, that's how much I bought mine for (I have 3, two at home and one in the office), the price in Greece is good up to 25 euros, after that it seems a bit hidden.

If you only want a radio, you can get the Panasonic RF-2400D which is very good and cheap.

Very good little radio up to €20. You can find it for €15-20 from China. If you find it up to €20, I recommend it!!!
Apart from good reception on fm/am/sw (maybe with a homemade dipole for help with reception), it also accepts a memory card, has a line in to connect a mobile or anything else, and of course, an output for headphones... Very good!

Honest little radio. I've only had it for a few days and I'm quite excited about it. My wife gave it to me as a gift from abroad. Its price was €17. I live in a big urban center, so the FM reception is 5/5, the medium wave (AM) reception is 4/5, and the shortwave (SW) reception is 2/5. With a makeshift dipole antenna, the shortwave reception is significantly improved. It has a rechargeable battery, the same as the old Nokia phones. With a memory card, it can also function as a "tape recorder" as it can record both radio programs and live speeches. If you find it priced around €20, buy it without hesitation. With the €35 that I see it in Greek stores, a big NO. With that money, we can go for much higher-quality products.

UPDATE (Nov 3, 2021): I accidentally discovered that due to a "flaw" in its software, I was able to access the VHF band!!!! Check out the link below!!!!

A very good and affordable small-sized radio with a powerful sound, including bass and high-quality sound. It is easy to use and you can directly enter the desired frequency without having to search, also the battery, which is the same as the well-known Nokia blc 5, left good impressions. The only negative aspect might be that I expected better sensitivity on FM compared to other radios like Tecsun. If you are in an area with a strong signal from radio stations, feel free to prefer it, it's worth buying (at a bargain price, not over 20€).

Be careful with battery charging, I left it uncharged for a long time and as soon as I put it on charge, after 2-3 minutes, the battery cover popped off because the battery heated up and swelled. Do not leave it completely uncharged for a long period of time.
