It doesn’t have keyboard, only remote controller.
WiFi doesn’t work stably.
It doesn’t have bluetooth.
It doesn’t have microSD/TF card slot.

The COSMOTE application (which was the main reason I got it) doesn't work and when you see it through the BROWSER it is very slow and freezes every second. It says it has Android 10 but the COSMOTE ott that runs 8.1 or later doesn't work.

First of all, it doesn't have the regular remote control and the keyboard doesn't work properly.
For example, the enter key doesn't work (it simply adds the letter q when pressed),
the right and left click buttons on the pad don't work,
it doesn't shut down, but always restarts.
The wifi is very slow (even though the modem is right next to the device), so live streaming is only possible with a cable connected to the router.
It doesn't play Ertflix because Ert has a problem with Android 9 after the latest update, as I can see on their Facebook page and other sites. And it doesn't work at all on Android 10.
It heats up quickly.
If I had kept the shipping package and the receipt, I would have returned it.
Maybe it's just my device.

They offered to replace it, but I didn't do it because I don't think it's a fault of the box. After a month, I have noticed differences in terms of delays depending on the quality of the video being played.
In the end, we put it in the bedroom with an external hard drive and we watch movies that we have converted to less demanding formats and news, and it's okay.
It also works better with a network cable, even if you place it next to the router, the wifi doesn't work well.
We gave it 3 stars because the quality of online videos improved with the use of a cable
