The first product I returned. The sound and build quality seemed satisfactory, but I didn't bother much because it broke the next day.

In terms of manual station storage, it failed miserably! And the reason I chose it was precisely for this feature. It has a list of Greek stations, but two were missing that I wanted - however, no matter how many variations I tried in the URL addresses, it couldn't find anything. When a station disconnected from the aforementioned list, I decided there was no reason to bother.

Furthermore, the interface is simply tragic! Someone unfamiliar with electronic devices will suffer (so it's not really suitable as a gift for an elderly person... which is actually why I wanted it in the first place). A buyer mentioned the app airMusic, but the capabilities it offers are limited (and no, you can't add stations with URLs through the app on your phone... you have to type it by pressing the buttons on the device... moving from a to z... and then from 1 to 9... and then a bunch of symbols... for each digit... it's driving me crazy!).

Very good quality-price ratio. The sound, although not very loud, is quite satisfactory and can be further improved with equalizer customization. There is the possibility to connect headphones with the classic audio jack. Full access to all device functions from smartphones through the free AirMusic app. In addition to the functions mentioned in detail in the product specifications, there is also the possibility to manually add stations using the corresponding URL. I would recommend it for purchase.
UPDATE AFTER 3 YEARS OF USE:
It continues to function without any particular issues.
How to add stations that are not available on the device:
By creating an account on Media You (https://www.mediayou.net), go to the Radio option (always on the web page, not on the device) and enter the wireless MAC address of the device and the name you want to give it. The process is not complicated. There are detailed instructions on how to find this address from the device. Once you do this, you can add stations on the web page, which will then be available on the device in the MediaU menu. I have added stations that were not previously available.
