I bought it to watch Netflix, which doesn't work after the update.
After a lot of searching, I installed Netflix on Kodi, which is the application on the TV box, and it works perfectly

I was reading good reviews and I messed up. You need to find the right Netflix to play PLEX, it still doesn't work, that's why I got ERTFLIX for nothing. I tried for a custom rom... I have another one bought 5 years ago for 30 euros and it does everything. Oh, the wifi only works next to the router. If someone wants it to put a disk and watch movies, that's the only reason

After a year of daily use, I can say that in terms of value for money, I don't believe it can be compared to any other TV Box. With a 50 Mbps internet speed and connected to 5GHz Wifi, its speed remains consistently between 45-49 and I haven't encountered any issues with streaming. YouTube, Netflix, everything plays in the highest resolution available on the platforms without any lag. The only somewhat negative aspect is its Wifi range, meaning as soon as it moves a bit away from the router, the speed drops immediately (at least on the 5GHz frequency that I use). Its usage for someone familiar with Android devices is almost identical to a mobile smartphone since most applications are available on the Play Store and in combination with Android 9.0, all the latest versions of the applications are also available.

It streams only YouTube from the mobile. I couldn't manage to play other videos, such as from Facebook, Dailymotion, etc., from the mobile to the TV, and Dailymotion directly from the box has terrible image quality. It is generally very difficult to use, it doesn't have a power on/off button, and the first time I connected it, it didn't turn on. I had another smart box and it was much easier to use and allowed me to play from the mobile on almost all players.

Second box I buy and this one is great. It doesn't freeze and with a 50Mbps connection, it's as fast as a mobile phone. It has Bluetooth and easily connects to other devices. It also has a power off option, not just standby. I have it permanently connected with an ethernet cable. It's worth the money, but I don't know how it will perform in the long run. The only downside is that it gets hot and you need to place it on a fan base.

I am inexperienced with boxes. I installed a Kodi Build called mana lab, I think.
At some point, the processor overheated, causing it to freeze, so I added a USB fan for 6 euros to cool it down, and it hasn't frozen since then.

I have it for almost half a year now. It works perfectly fine. It has been very convenient for me. Personally, I installed Viki Rakuten, Crunchyroll, and VLC. I had to side load Viki Rakuten from a USB stick because it wasn't available on the Play Store. I just installed Crunchyroll today. Someone mentioned that the Play Store has stopped working, but it works flawlessly for me. The latest operating system update was done in late November - early December, around that time. Overall, it works without any issues. I bought it for 65 euros and I think it's definitely worth the money. However, the menu could be easier to navigate.

NOTE: It has Bluetooth, even though it's not mentioned in its features. I was surprised when I connected my Bluetooth headphones. I thought it didn't have it.

I bought it for 55€, let's say it was a good price. When I connected it to the internet and tried to update it, there was nothing to download. I opened Netflix and it told me that the application needed an update. I tried to install the new one, but the response was that your system does not support this upgrade. Additionally, the wireless mouse I installed was not working. I contacted the company and they gave me the support email of another company. In their response, they told me that Netflix is a 3rd party in relation to Android and it's not their fault (note that it's Android 9). Nevertheless, they sent me a link for another version which surprisingly worked well, and I changed the mouse as well. I have to say that after two weeks of inconvenience, it finally works well.

I bought it mainly because of the positive reviews that existed, but the impression I have so far is negative. It is relatively difficult to handle, I have connection issues with airscreen, the NETFLIX application cannot be updated (you should not accept the update because newer versions are not compatible), the Wi-Fi only works if you disconnect the LAN (never both)... For the 60 euros I paid, I would not recommend it...

update 16/1/21
So far, the basics work well without disconnections and freezes (1-2 minor ones that were immediately resolved with a reboot). I have no issues with NETFLIX (I kept the older version, but there is no problem), while I solved the difficulty of handling it with an air mouse (you can get a good one for 10-15 euros). I haven't explored the other applications (e.g. KODI) because they don't concern me. Youtube, browser, all good...

I have had this specific android box (a subsidiary of XIAOMI) for about a year. I have not encountered any problems at all. In order for the Wi-fi to work on these devices, we need to disconnect the LAN cable. Although personally, I prefer LAN for better internet stability. It can be used as a hotspot for internet on other devices and additionally, it has Bluetooth. Regarding Netflix, you will need to download version 4.16.3 (after deleting the installed version) from the internet, which is in Greek, with sound and works without any problems. The 3 USB ports (one of which is USB 3) and the playback buttons (play, pause, stop, FFW, etc.) for audiovisual content on the remote control are a great advantage. Perfect in one word.

Connected to a plasma TV via HDMI. Excellent picture quality (for a non-HiEnd device), even from Netflix. The sound on Netflix is the usual average sound of Netflix, which makes it difficult to understand dialogues at medium/low volumes. I haven't tried Toslink. The device is generally user-friendly (like all Android devices). The main issue I haven't solved yet is that it crashes my PC's Kodi (the TV box's Kodi pulls from the PC's library). Also, when playing 4k movies from the PC with Kodi, it doesn't convert HDR to SDR, so the colors don't appear correctly on my TV (which doesn't support HDR).

Netflix is not available in Greek.
2. Difficult menu if you don't know.
3. After a lot of trying, everything works.
4. It's worth it.
5. Better with a wireless mouse.
6. In the end, it died... it doesn't work.
7. I searched for it... it's not the power supply, so it's garbage
